Sam has always slept on his tummy since about 8 weeks old - prior to that we used to have sleepless nights due to having to pace up and down the room with him in our arms, he would just not sleep on his back! Settling him was a complete nightmare, he would feed, take ages to burp, then about an hour to settle, and he used to feed every 2 1/2 - 3 hours! By the time we went through the process it was time to feed him again! I used to have literally 2 hours sleep a night in 10-15 mins intervals - and that's if it was my lucky night! He will be 6 months next saturday and still sleeping on his tummy. He settles himself, falls asleep within 5 mins of being put to bed - complete bliss! He still wakes up once or twice a night for a bottle, but he feeds, burps and back in bed all within 15-20 mins! My mum said both me and my brother were put on our tummies and we are both fine. And i always said happy mummy (because she is not a walking zombie anymore) means a happy baby!
