Hmm, ok then. My first bub was a great night sleeper but I was clueless about how much sleep he actually needed and he got very overtired during the day. With this one I thought I was more on top of it, the 2ish hours has been a gradual stretching out from an hour or so when he was new. I looked at one site with sample routines and it had 2 hours waking time but it is possible that he just needs naps sooner.
He does have white noise in his room but we have an open plan house so sound really travels. I feed to sleep and put him in his cot asleep which I know aren't helping him to connect his cycles on his own. I'm sending ds1 to daycare this week to focus on meeting ds2's needs.
