Hi

I would say 2 - 3 puches is around normal. My boy is now 15 weeks old and he's on 2 - 3 a day. he was also 1kg when he got his jag at 9 wks and when he went back for 2nd jag he was 1.8kg! I don't think you can overfed as i have had the odd day Mikey wont eat as much as he did a previous day think it all depends on how active he's been all day hehe. xx
