But the Younger star has found a new way to make sure Banks gets a good night’s sleep — meaning her and her boyfriend, musician Matthew Koma (with whom she welcomed her baby girl in October), get one as well. “We have a sleeping baby!” Duff, 31, wrote on Instagram. “Baby whisperer/ genius/ brilliant /calm and loving Kimberly (actually baby care specialist and postpartum doula) ( @sweetdreams.la ) spent this rainy weekend with us and got our sweet girl sleeping!” Hillary Duff/Instagram “I honestly didn’t remember what good sleep felt like! Pretty delicious!” she raved. Want all the latest pregnancy and birth announcements, plus celebrity mom blogs? Click here to get those and more in the PEOPLE Parents newsletter.

For Duff and Koma, 31, this posed a real problem when wanting to return to work, but also a cause of concern for Banks’ own health as well. According to Baby Center, newborns are expected to sleep anywhere from 16 to 17 hours a day, often for two to four hours at a time. Since hiring Kimberly Von Slomski, the postpartum doula and founder of Sweet Dreams LA, Duff said her daughter has been the happiest she has ever seen her, writing, “She slayed 11 hours last night and woke up with the biggest gummy smile I have ever seen!” Banks Bair.

She also shared an adorable Boomerang clip on her Instagram Story showing baby Banks now excited for her nap time. Slomski and Sweet Dreams LA have also helped former Bachelorette Ali Fedotowsky-Manno sleep train her now 8-month old son, Riley Doran. Last year, Fedotowsky-Manno opened up about the experience as well on her blog, writing that she highly recommended the training for any family that is able to invest in the opportunity.
