Thanks girls

Black rose - I did forget to mention he is good at putting on weight and is right where he is supposed to be, so I think I agree If hes getting all his food in the day and only having one feed during night instread of two I may leave him.

Turtleschell - We did demand feed early on but without me trying he seemed to set himself a routine, I have two other kids so there were times early on I had to offer a feed maybe a little earlier than he may have wanted it as I was going to be travelling to gymnastics / footy etc, so perhaps I did tend him towards certain feed times?
I agree not waking him for the 11pm feed is a good thing as he seems to want to be left sleeping and feed later in the night, which I suppose will end up getting later into the night and eventually he will sleep right through.
