Apologies if this has been covered before.
My DS is 5 and a half week's old, and for the last 2 and a half weeks he's had many days where he won't sleep much or at all in the day. I'm aware that a tiny baby needs 14-16 hours in every 24 hour period; on at least 5 days in the last 20 he's had between 7 and 10. His night sleeping is pretty good - he feeds at 11, back down til 3, then again at 6 or 7, so that's good. I wouldn't mind if this amount of sleep was all he needed, but it clearly doesn't as he gets massively overtired and then screams for hours on end.
I've tried going out in the buggy - he'll doze but ping awake as soon as we stop; a battery-operated rocker - he doesn't mind being in it but won't sleep; rocking him in my arms - doesn't work; just putting him down - oddly he is often quite happy to lie in his cot for up to an hour very quietly, but wide awake. I always swaddle him to sleep so can't try that. He literally spits out the dummy so that's a non-starter too.
Yesterday was one of these days - he woke at 8.20 am and finally went to sleep at 10 pm with only 1 hour down (6.30pm) and possibly 45 minutes dozing on and off in the buggy. He had 9 hours in total and DH and me took turn with him mainly screaming and flailing from about 4.30 pm til 10pm. On the day after a day like this he is invariably knackered and in fact is asleep again now.
In all other respects he seems very happy and healthy - not surprisingly he is very alert, his weight gain is very good, and the bf is going really well. I am happy to fit in with his needs, but I just do not think this can be right! Any advice gratefully received.
