I still cut up fruit for my 13 & 11yos.
They eat well, but since going to secondary school where it seems to be the norm not to eat any fruit or veg at all, it's not always easy to make sure they their 5 in the 2 meals I still have control of. TBH, I'm not convinced about 5 a day anyway, all the research says it should be more...
If I ask them if they'd like some fruit they'll say no. I have a full fruit bowl but they don't touch it. If I slice up a couple of pieces and leave it next to whatever screen they're using, it soon disappears - I have to assume it's being eaten.
So, stupidly pandering and babying them, or sensible way to make sure they get what they need?
