Hi Tan

Pip was like this a little, and he started wanting to sleep on his tum. He'll now sleep OK on his back if I'm holding him, but putting him into his cot, tum's the only way to go. As he's able to roll, he moves onto his side etc.

Another thing is maybe put a toy in her cot? I have a big cube with handles and rings etc on it, it keeps him amused and he often falls asleep clutching it. Also when he wakes in the morning, he'll play for a little while by himself. That's in addition to wrestling with his bear

good luck!
