Thanks girls.
My health visitor said the same about stage 2 formula, but I thought she was just being over cautious because when i asked, Matthew was only 3 weeks old. However I know a lot of people that do use is already, (yes wobs, your one of them lol). Maybe I'm over thinking it to much, even with my 3rd baby I still worry about everything

I have half a tub of Aptamil first left so I'll use that and maybe just switch to another milk but stay with stage 1 for a while longer. Also I might give the Avent no2 teats a try, perhaps then he'll take 5oz instead of 4 and then not want to be fed before the 3 hours. I thought by now he would be going 4 hours not wanting it after 2.
