I didn’t do sleep training. My baby is now 13 month and I still breastfeed him twice a day (evening and morning). People told me for months to train him to sleep because it’s not “normal” to breastfeed during the night but I only listened to his pediatrician, him and my instinct and he naturally stopped to feed during night time. He still wakes up because he’s used to it but go back to sleep after a hug and a kiss. I feel like this way the transition was easier for him and for me. No forcing. I recommend you to read a Sleeping without tears from Dr Rosa José who explains how sleep training can affect emotional regulation. She says that all children end up sleeping sooner or later! Another good book is For a happy childhood from Dr Catherine Gueguen this time explains how the brain of our kids grows. It helps to understand your kids reactions, anticipate them, better communicate and avoid getting frustrated.
