Food before daughters swimming lesson

Personally, I’d give her something like cheese & biscuits straight after school and then something like a bowl of soup or jacket potato after swimming.

I would give her a snack beforehand then dinner after swimming
Eg peanut butter or cream cheese on toast, a bowl of whole grain cereal with milk, some malt loaf...nothing too heavy or hard to digest

Snack after school, before swimming...

-Bread sticks + babybell cheese
-Cucember, carrot, Pepper with houmous
- Fruit + Cheese chunk
- Dry cheerios
- 1 piece of toast

Then a normal main meal after swimming... Any reason its a "light dinner"

Favourite after-school snacks in our family:
Yogurt-covered raisins
Boiled egg
Apple and peanut butter
Flapjack/cereal bar (my DD likes the frusli bars)
Pasta salad
Half a bagel with cream cheese
Frittata muffin
Slice of pizza
Sausage roll
Instant porridge

Our lessons are 5 and 5.30, mine have been having fishfinger sandwiches or quick pasta at 3.45, then crackers and cheese or similar at home after 6. 30. They don't do well having one big meal on these days so two smaller efforts is good for us.
