She has much the same thing every day:
a sandwich - 2 slices of bread with grated cheese
an apple or a pear
a slice of cake or 2 bought biscuits (eg digestives or hobnobs)
a carton of milk
(Sometimes she will also have a small pot with an extra thing eg crackers / dates)
She also takes a pot of porridge for breakfast as she leaves the house very early for swim training and eats it when she gets to school.
This is what she eats until she gets home at about 4, and she'll make herself a hot chocolate or a piece of toast.
It's not that much is it? She's very active and a healthy weight, so I'm not worried so much as curious. She's rather young for her age and has started to notice how her friends are talking about how much people eat. Apparently the consensus is that she eats more than anyone else
