OK, I have finally learnt about sleep regression and believe that is what we are going through right now. I just wanted to post this in case anyone has ideas or at least to let us know if we are on the right track with what we are doing.
Our DS will be 4 months old this Friday and has unbelievably been sleeping through for at least 8 hours... until last Sunday
. We have had a week where the longest spell of sleep at night has been 2 hours the shortest, every 15mins between him sleeping and waking. He sleeps in his cot in his own room and we have been going in trying to settle him at which point he goes back to sleep very quickly and clearly is in distress not just crying for attention. I have not offered the breast only when I can tell he is hungry - nuzzling rather than trying to nod off again which is usually only once a night about 3am. I have also not taken him in with us as I think it would be a habit that may be hard to break
.
He is also teething which gives him grief so we are applying some teething gel when he needs it. I have given him some liquid paracetamol occasionally when I can tell he really is suffering but this is in the daytime not at night. Oh, and on top of all this he gets a blocked nose due to his crying which really annoys him!
In the daytime he is not really sleeping to catch up on the lost sleep, yesterday was a miracle, he got 3 hours in one stint but nothing noteable during the week other than that.
I know this could last a while and really feel for him but whilst this is happening getting more than 2 hours sleep in one night would be nice.
