DS1 (5 1/2yrs) is in kindy (his first year of formal school). Today he came home and told me his teacher told him to tell DH and I that we need to give him more food in his lunch box. I asked him why she said that, and he said because he ate it all at lunch time (at this school, they have lunch first and then recess break later). It came out later over dinner that she gave him $1 to get something at the canteen for recess, and he chose to get a slushy.
Now I have several issues with all of this.

1) I give my kids heaps of food for their lunch boxes- usually a sandwich, a piece of fruit, a piece of cheese or yogurt, a packet snack like tiny teddies or crackers, and a home made snack like a muffin/biscuits/slice and water.
Before school, DS will have cereal at home for breakfast as well as a cup of weak tea or hot chocolate, and then has a slice of toast at school with his friend from the canteen. The kids get a fruit break in the classroom, and DS said he eats his fruit and part of something else in his lunch box.

2) Why isn't the teacher watching the kids to see the amount of food the eat and encourage them not to eat it all at once. That's A LOT of food for a 5yr to pack away at once. When DS's at home, he's content with his sandwich and a bit of fruit for lunch.

3) I appreciate that the teacher didn't want DS going hungry at recess time and that she was being kind in giving him money, but why would you think a 5yr old would choose something substantial or healthy to eat when he can go and buy slushies or ice creams (etc) with the money? If she had have gone and got him an apple or something like that, I think that would be more appropriate.

4) We only give our kids canteen money once a fortnight, or less. I don't like them eating canteen food often, and they don't need to eat it, since we have our own food at home which I take care in making and ensuring is fairly healthy. I don't want DS thinking he will be given money when ever he finishes his lunch so he can go and get junk food.

Am I over reacting? Am I feeding him enough? (It's seems to me, that he gets plenty of food, more than I remember getting in my lunches!). Do you think it appropriate that he was given money by the teacher?
I am going to talk to his teacher tomorrow.
