So my son is now 7 months old and he has officially decided to be a belly sleeper... 😥 He's very much capable of rolling over from belly to back and vis versa but it still makes me nervous to leave him on his belly. Sometimes I'll turn him back over but of course it wakes him up and then it's hell trying to put him back to sleep and he just ends up back on his belly anyway and it's not like I can watch him all night... 😒 At 7 months is it still really bad for him to be on his belly or am I just over worrying?
