Dd2 is only just 9, on a typical school day she has
Small bowl of cereal (with or without milk, depends on her mood) and a very milky cup of tea.
Sometimes an apple to walk to school with
Tuck at break (cereal bar/biscuits/fruit type things)
Pack up of... sandwich2 slices with ham as filling, cut into whatever biscuit cutter shape she picks; fromage frais, raisins, home made bun or similar, mini cheddars or crisps. Sometimes cocktail sausages, sausage rolls or popcorn, more often not. She doesn't often deviate from the basics.
Piece of fruit or another small bowl of cereal when she gets in.
Tea - pie, chips and veg tonight. Small packet of malteasers for a treat; we don't tend to eat sweets or chocolate through the week.
She's very picky & perfectly happy to eat the same things every day if I'd let her.
