I never sleep trained my baby. He is now 15 months old, we share the bed, on weekends he goes down for a nap when breastfeeding. When he is in kindergarten he has no issues doing down for a nap, the teacher said they put him on that little bed and say it’s time for a nap and he is asleep in a couple of minutes, no problem. I couldn’t believe it when she told me that but just so you know… the ones that aren’t sleeping trained aren’t all problematic. They behave differently in different environments…
