i know the advice is to sleep on their backs but is it really dangerous for babies to sleep on their side sometimes? DD is 7 weeks and at night after feeding, she drops off and sometimes, i am too dozy to roll her ono her back. she also sleeps on her side sometimes during the day, when we are at home tofther. she has reflux and seems more comfortable. also, when she vomits, it's less likely to choke her and come through her nose.
is it really unsafe?
