Ds is now 6 and a half months old and he wakes every morning between 3 and 4 am. I get him into bed with us and most of the time he will fall back to sleep but other times if he seems hungry i get up and feed him.
Hmmm, this sounds familiar. If you don't have to feed him every time, this tells you that he can sleep through. We had similar with ds. I made sure he was getting enough milk during the day and especially before bed. I also still dream feed him. I then assumed that he was waking up out of habit, so I felt that I needed to stop rewarding his waking and instead of picking him up (he wasn't crying, just awake and wanting us to go to him), we just gave him a dummy. He soon twigged that this was not really worth waking up for and he started to sleep through after only a few nights of this. Also, dp went instead of me as I was convinced ds could smell milk on me and would then want some.
So, in short, don't reward him for waking up, don't take him in with you if you can. I know it is tempting if it is the only thing that works or hey, because it is just so nice to have them snuggled next to you but it is worth waking up for him.
jbad - mine was doing that when she was 5 months old and did it for 5 weeks till i introduced her a third solid meal and now sleeps thru (but the mo she is on solids strike so she is waking me up again!)
Had she been like that since she started on solids?
Is it getting light then?
Birds singing and window open?
Happened to me for 7 weeks last year until I slept in dd's room and realised that nesting sparrows were right outside her (open) bedroom window. They were deafening!
