DS is now 5 months old and has been waking 1-2 hourly for the last 2 weeks as he can roll from his side (preferred sleep position) to his tummy, but cannot get back.
I have got rid of the wedges as he wriggles out of them, and if he is on his tummy, I just pat him in this position. Sometimes he will go to sleep like this, but more often than not I have to flip him over and this will often wake him up fully and it takes ages to resettle. I end up feeding him once during the night (other than the DF) as there is always one period where I try to resettle for over an hour and find that a small feed (3-4 oz) makes it easier to get him back to sleep.
I rock him till he gets drowsy and then put him down on his side, and he will then roll onto his tummy or back and cannot get to sleep.
Like someone else who posted earlier, he is often not upset when I roll him over, he just looks up at me smiling. I try to leave him, but he will soon start crying once I have left the room.
I am giving him lots of tummy time during the day in the hope that he will soon learn to roll back from tummy to side or back and be able to resettle himself. He has not slept longer than 3 hours at a time in these last two weeks so I am really hoping it will get better soon. It does make it easier to know that others are experiencing the same thing.
