My baby is 7 weeks old and slept through the night for 2 weeks, sleeping for between 8-10 hours (which I know is really good at his age). He has now reverted to usual sleeping of waking up during the night, so I've been giving him a bottle which he has been taking. I felt great and like a new women while he was sleeping so well but can't understand why he's reverted and I feel gutted as I feel he has teased me with this great like then thought no you're not having it that easy
. I have to hold him until he falls back to sleep and then transfer him so I can be up for about an hour each time. Any advice on how to get him sleeping through again or why this has happened? I'm swaddling him in a sleep bag and playing white noise. He is not going through a growth spurt I don't think as that has just recently happened.
