I wanted some mommy advice so i have a 3wk old nd i was wondering if it would b ok to let her sleep on her stomach as too she seems to b more peaceful then on her back as to she wakes her self up because she moves her hands alot. But me as a new mom worry she may suffocate even though she hasnt given me any signs she would from the couple times during the day ive let her sleep on her stomach. What do u guys think
