I agree with Mooshie, a lot of times kids browse and snack during the day and really aren't that interested in eating a lot at one sitting - this doesn't mean that they aren't eating, it just means that they have different eating patterns to an adult - which makes sense if you think about it. If your husband is concerned about him getting thinner, it's probably because he is getting TALLER!

A couple of ideas I used to get the children interested in food at a young age was to make dinners of finger foods, sticks of salad vegetables arranged in a face with sausages cut into circles arranged around the side of the plate as hair, stuff like that. Faces of people or animals were always popular, and I still do it if I have 'fussy' kids over for dinner.

If you are concerned about getting vegetables into him, how about making vegie fritters with a little flour and egg, with grated cheese through the mix to make it tasty?

Do try not to get too stressed about it, these things come and go in phases and if your child is truly hungry, they WILL eat. If his intake has dropped off noticeably, it probably means he has just finished a growth spurt and doesn't need as much food right now, it will probably change in a matter of weeks.

Good luck!
