Lera Deriy,

attachment-based child sleep consultant,
birth to 7 years

Huge thanks to Valeria Deriy for the consultation! I have studied a lot on the topic of sleep and doubted for a long time whether to take a consultation, thinking "what new information will they tell me?" and "the child will cry anyway, and I don't want that, so there's no point." Valeria is gentle, warm, and understanding. She provided a lot of new information and built my further actions step by step according to my request. There was no pressure or judgment, and she answered all my questions, even those that hadn't yet arisen.

After the consultation, I felt a surge of strength, confidence, and hope that it would be possible to improve the baby's sleep, and we are already moving towards this. Before the consultation, the baby slept only in my arms, but now I can put her in the crib without waking her up. I highly recommend Lera as a sleep expert!

It is very pleasant to deal with a real professional who accompanies you from the beginning to the victorious end! All the advice was helpful, and Valeria is always in touch to help and encourage! My family is sincerely grateful to Valeria for her work!

1-hour consultation
My first child is highly sensitive, and I read a lot of information about infant sleep both in Russian and in English-language Internet and had previously contacted BabySleep to improve sleep. The situation with the second child's sleep is simpler than with the first one, but there was (and still is) a problem with short daytime naps, which I could not cope with by myself.

In the format of a 1-hour consultation, based on the data from the sleep questionnaire of my youngest son, Valeria Deriy offered options for correcting the rhythm of the day, which I myself would not have dared to do, fearing oversleeping. She also answered a number of other questions about the sleep of the youngest child and gave recommendations for the eldest. Lera impressed me as a competent and attentive specialist, I am happy to share my review and recommend her!

Lera is an absolute treasure. She is the perfect, competent, and level-headed consultant, always there for you, always knowing the answer. It seems to me she knows absolutely everything about children in general: about approaches to them, about methods, about the pitfalls of those methods, and even everything about parents)) Our little one isn't very fond of sleeping. Lera helped us with sleep at various stages, starting from 5 months up until weaning and independent falling asleep at night. Our baby is on a schedule, and we parents are disciplined, but we still regularly hit periods where sleep would just fall apart. We never understood why, but Lera would always explain in detail and clearly what was happening and what could be done. She invariably found the exact thing that worked for us. We followed Lera's instructions precisely, and the situation always improved. To this day, I feel that if it weren't for her, the collective sleep deprivation in our family would have lasted for weeks, because when the baby doesn't sleep, nobody sleeps))

Consultation with support
Valeria Deriy responded to my messages very quickly and gave detailed comments that helped to understand the situation with my daughter's sleep and improve it. Valeria was very interested in getting a positive result and although working on my daughter's sleep was difficult, Valeria never gave up. She was very supportive and tried to give me as much information as possible applicable to my situation and a little perspective on possible future changes / difficulties as the child grows.

Many thanks to our consultant Valeria Deriy.

Despite the time zone difference, which is 7 hours, I never felt abandoned for a day. I always received detailed answers, support, and next steps.

I had many requests, but we worked through everything, not a single question was left without an answer or explanation. It was easy and comfortable to work. Valeria was always in touch supporting and clarifying next steps.

A miser pays twice! It is better to contact a consultant right away, where you will not only get the solution, but, thanks to the new option, will be supported further for long-term result. And this played a decisive role in making the decision to work with Valeria.

Individual approach! Everything is prepared with a minimum of general phrases. Everything is structured and discussed with Valeria Deriy down to the smallest detail. Everything is clear and, it seems, easy! I would never have thought that we could solve our problem in just one consultation. Thank you very much!

Valeria Deriy is a very sensitive and attentive specialist. I was afraid to start teaching self-sleep and put it off for a long time. It seemed like it would be very difficult and unbearable. Valeria explained both the theoretical part of the issue and all the practical steps. She went through with me step by step how to act: take the baby in your arms, do this, then this, and if suddenly this happens, then do this. With a clear breakdown by time.

With my first child, I co-slept with him until he was almost 9 years old. With the second, I decided to try to make sure the baby slept in the crib so that everyone could get enough sleep. We started training at the age of 10 months. It took essentially one day for the acute phase, that is, when the child does not yet understand what is expected of him and why he now needs to sleep in the crib. It was hard for me to endure the tears and, as it seemed to me, the suffering, but with Lera's help, I realized that these tears were tears of getting used to.

The baby's dad or I were always next to the crib, comforting, helping, and not leaving. No one left the baby to cry, no. As a result, on the second night, the baby slept much better than he had in his entire life before. We are still in the process of learning, but I can definitely say: I have my own life. I can put the baby to bed and do my own things both during daytime naps and when I put her to bed at night.

Before, I literally could not go anywhere; there were no evenings because the baby woke up every 40 minutes. It seemed normal to me, and I thought I had to be patient... Now I understand that I shouldn't have, and I should have immediately asked for help.

Thanks to Valeria for her sensitive understanding and support!!!

Valeria Deriy helped twice. Once with naps, the second time with weaning from drinking formula at night. My son woke up every two hours at night, now he sleeps all night.

I am very pleased! I didn't even think that the results would be so fast. Of course, I still must work on the technique of putting to bed, but the principle of action is clear. All of Valeria's recommendations work!
Valeria, Barcelona (Spain) / Daughter, 1 year 6 months old

I was very glad to have Valeria as my consultant. I have a baby 18 months old, and she was waking up every 2 hours at night, 4–6 times. And she could fall asleep only with breastfeeding. I was very tired but didn't want to use hard methods like “crying out”.

So, Valeria helped me to correct the hours and activity. And gave me a lot of useful information about food, psychological behavior etc. She was really deep into my problem and always responded quickly and explaining everything in detail.

So for 1 month of our work, we improved a lot of our nights. My baby sleeps now first 5–6 hours in a row and wakes up 2 times per night. And she learned to fall asleep herself. And no tears at all during all changes! I highly recommend Valeria!

Lera, hello! Thank you for your consultation and for convincing me to enroll in the online course. With the help of the online course, many questions in my head began to resolve themselves, and the information that I received during the consultation with you has now settled on the shelves.

We taught our son to sleep under the sensitive guidance of Valeria Deriy. It was clear that she was worried along with us and really wanted to help improve his sleep. We tried all sorts of methods until finally it worked.

Now we turned to her again for a consultation because his sleep suddenly got out of whack. And lo and behold! The very next night after the consultation, my son slept well! Valeria gave us tips and advised us to pay attention to subtle moments that we simply don’t notice in the pace of life. We thank her with all our hearts! And we send greetings from Kirusha!

Valeria Deriy helped our family a lot, thank you very much! She gave recommendations very softly, delicately, and tactfully, and supported our spirit. The result is excellent. Before, Kira woke up 6-12 times a night and slept no longer than 1.5 hours. Now, she wakes up 1-5 times and sometimes sleeps more than 7 hours continuously. Amazing! I am very impressed and glad that I decided to choose Valeria.

We turned to a specialist for a one-time consultation between one online course* (0-4 months) and another (4-18 months) to understand whether we were doing everything right, experiencing sleep regression at 4 months, and in general whether we were doing everything well and using the course material correctly.

I really liked Valeria’s approach to such a non-specific request. She found an approach specifically for us, explained everything very clearly, and gave advice on the best time to introduce the regime and self-sleep (at what age in our case it is best to start). She helped to outline our roadmap, so to speak.

I have been reading various sources about infant sleep since my daughter was born, from 1 month I established her sleep in her crib in her own room without strong associations. But after switching to one nap and a lot of traveling, the quality of her night sleep worsened. I spent a long time looking for the reason, shifted the awake period, but did not see any noticeable effect.

Valeria Deriy helped me understand that my daughter’s schedule is fine, that she can safely keep the evening awake time of 6 hours, and she told me how to wean from the 2nd night feeding, which helped that same night. She also gave valuable advice on how to finish breastfeeding.

It was very pleasant to communicate with a professional for whom family, psychologically healthy atmosphere at home and quality of the sleep of both parents and a baby are important.

Anna, Perth (Aurstralia) / Son, 9 months old

I highly recommend Valeria Deriy as she has been very professional and helpful through all the time we worked together. My 9 months old son used to wake up 2-4 times at night and co-sleep half of the night with me. During the day he used to cat naps for 30 minutes. Also I couldn’t put my baby to sleep without bouncing him on the fit ball.

After practicing very gentle sleep method my son sleeps from 7pm to 7am in his cot with one wake up for feed at 5am. His day naps became longer and sleep schedule is more predictable now. Ethan have learned to self soothe and I no longer need to use fit ball. Except during teething or growth spurt I was going back to bad habits bouncing on the ball or co sleep. It’s not an easy work but it’s 100% worth it and it’s not stressful for the baby as sleeping method is very gentle.

Valeria is very sweet and kind person and has lots of knowledge about baby sleep, development and more. It was very easy to communicate with Valeria and she was always there for us. Valeria always responded with very detailed information. I am very grateful that I had a chance to work with Valeria.

I am very grateful to Valeria Deriy for her support, patience, and calmness when I was already very worried. We have done a lot of work together, but there is even more work ahead. My child turned out to be not at all simple, although it seemed that there were no special problems. But Lera did not give up and guided me.

Thank you very much for being there. Teaching a child to self-sooth independently is not easy, but it is possible, the main thing is not to give up and not to confuse the child! Special thanks to Valeria Deriy, she is very attentive and explains everything thoroughly!

From the first minute, my husband and I felt that Valeria Deriy is a specialist in her field and knows how to lead us to the desired result. During the work, this feeling did not go away and supported us. Valeria knows how to listen and pays attention to nuances, sees them, this allows us, parents, to better understand the situation, make a decision. Valeria knows perfectly well how to support with words and deeds. An extremely empathetic and delicate person.
