Mine has been sleeping on her tummy since a few wks old, she's 8 wks now

My son just now started sleeping on his tummy he's almost 10 months old! My almost two year old he sleeps on his tummy to. It used to make to nervous but most the time my youngest will roll back on his back

However baby is comfortable

Omg, I slept on mine, as a baby, my 3 boys where on there's, where all ok lol if it makes u feel better do it during nap time so u can watch and see. In the end it's what you feel comfortable doing.

You do what makes you comfortable

My son can hold his head and switch sides but people keep scaring me with their sids stories and theory's @mom04 @babes101116

As long as there on a firm flat surface without cushions and blankets everywhere, and they can hold there head up and turn it side to side, for me I think there more comfortable.

My kids always slept on their stomachs
