okay I know alot of people out there may be really against this and think i'm a bad mommy but i have a new baby who has been very difficult to get to sleep and stay asleep ... so tonight i tried the unthinkable and placed her down on her tummy to sleep and it worked like a charm she is still asleep and i have kept constant watch over her-- is this a bad idea? am i the worst mother ever? feeling guilty, but also feeling tired...
