My 4m old has always been a really good sleeper and has slept through the night from 13 weeks, although we do often have to get up to replace his dummy. For the last few nights he has been waking up any time from 2 til 3am and chatting loudly for upwards of an hour. He is so noisy that it is waking us up, although he is quite happy. Last night I fed him after an hour and a half but he carried on chatting afterwards for a bit, then didn't want his morning feed, so I don't think he's hungry. We don't use a monitor, but have an angel care apnoea matress with an alarm and we live in a small bungalow, so noises are easily heard. My DH has gone in a few times to give him his dummy when he has been chatting, but I don't think this is a good idea, and think it might make DS realise that he can get our attention easily through the night when he doesn't really need us for anything.
My question is - has anybody else experienced this, is it a developmental phase, because he has just discovered his voice and chats a lot in the daytime too, and how long will it last? I'll be getting out the ear plugs tonight I think!
