His teacher gave him money for the canteen

That's one thing I had thought too, familyof3. I don't *think* DS would do that, but it's a possibility that he might click that he will get money for junk if he chucks his healthy homemade stuff.

I talked to the teacher today, just 'Did he have enough food today?'. She kind of looked at me blankly, and I said he told us to give him more food because you said he didn't have enough, and gave him money. Then she said yes, he had enough, and I asked if he gave her the money and she said yes, and thanks. I thanked her, and I told her he got a slushy with the money and I was not really happy with that, and she said to him 'I told you to get a piece of fruit or something healthy!' So she did kind of try to get him to get something healthy, but seriously, a 5 yr old with money to get what he wants...?? As if he's going to buy an apple when he can have a slushy!

FWIW, he didn't even eat the extra food I gave him. He's just had it for his arvo snack. I didn't think he'd have that much, I don't think DH would even eat that much food! So he must have just had an extra hungry day.

I'd probably start packing more food in his lunch box. Maybe divide it into 2 so he knows what is for what.
5 is about the age that both my children had a growth spurt that saw them eating pretty much the same as an adult some days.
I certainly pack more than that into DS1's lunchbox because he likes to eat a lot at school. DS is a lunch skipper so he has less and anything leftover is his afternoon snack unless his brother gets to it first.
