Hi my blw 13month eats LOADS of certain things (macaroni cheese, bread with philly for eg). I thought they stop eating when they have had enough so was just giving him as much as he wanted, but my mum said he might just be being greedy and he shouldn't get used to having such big portions. Anyone had any experience of this? I don't want to end up with a 10 stone 5 year old who I have to wheel to school...how much is the right amount?
