I've just read that apparently the current advice is 'back to sleep, tummy to play' now I'd heard 'back to sleep' but had no idea about putting them on tummy to play! Apparently you're meant to do with every day? DS is 11 weeks old and i've never done this!
Well, I've just tried and he screamed. Can't see it ever working. How important is it? Please help, worried now!
