Our 4 1/2 month old ds has a habit of wriggling around in his sleep and ends up with his head up against the side of his Moses basket, then wakes himself up because of it and cries. So we have to get up, shuffle him back down, and he'll generally go back to sleep (unless it's getting near waking up time in which case he needs a bit of a feed to get him to go back down).
Last night we moved him out of his Moses basket and into a travel cot so he'd have more space, assuming this would solve the problem.
5am this morning I hear crying and he's wriggled himself sideways, so he's head's up against the side of the cot!!!!!!
We gave up on using sheets/blankets as bedding long ago because he'd wriggle out of them and wake up cold as well as at the top of his basket, so he's now in a sleep bag - so at least he's not getting cold from his nocturnal movements.
While this isn't the biggest problem in the world, and I'm incredibly grateful that aside from his nighttime headbanging he does sleep through, it is really annoying.
I'm currently considering supergluing his sleep bag to the mattress!!!
Any alternative suggestions would be much appreciated.
