I need to defend the unloved, unpeeled knobbly carrots!
They are washed by TAs in the morning, as are the other fruit, so just the same as an apple or pear in that respect. When you eat it you can break the carrot in half, chomp down to nearly the end of one, then the other, then throw the two ends away. Our children love them.
I can just imagine HTs being willing to pay support staff to come in early once a week to peel and slice 250 carrots because some PFBs don't like them any other way
Op - couldn't your dd have a snack in the playground while you are waiting to go in? Or milk to drink at snacktime?
