5 month old is going through what I believe is sleep regression (used to sleep quite well at night prior to this). He has only ever napped for half an hour max in the crib and does remainder in my arms. My husband works very long hours and I have little family support. I'm running on very little sleep and exhausted (which I assume is just life with a baby). Is there anything I am missing here which could assist me in getting sleep? The only thing I think I am missing is that when DH is home he could take the baby for a bit but he cannot settle him at all when he cries, or cannot rock the baby how he likes in order for him to fall asleep for a nap and this has always been an issue for us. Is it a case of me just being a zombie for some time and eventually I'll get my sleep back?
