For your comparison - DD 8 years old. Today (a school day) she had:
Breakfast - Huge bowl of shreddies with warm milk
Break time - 4 crackers with butter
Lunch - ham wrap, pot of grapes, greek yogurt (I used to put so much more in her lunchbox, box she would eat crisps and chocolate over the healthier options saying there isn't enough time to eat it all and have a decent amount of time to go out to play)
Dinner - 2 big sausages, roast potatoes, broccoli, carrots, cabbage & snap peas (a few raw snap peas and cabbage before I could get it in the pan because apparently she was starving)
Dessert - Jelly and ice-cream
Snacks - Orange, plain wrap (she loves plain bread with nothing on it) packet of crisps (asked for grapes but we've ran out
She often eats Weetabix for breakfast - she has 3! She also has milk before bed most nights.
On a weekend she eats more snacks in between meals - boiled eggs, fruit of any kind, raw veg sticks, sweets, sausage rolls, nuts. Basically what ever she can get her hands on. I don't mind because she is generally an active kid. I only say no to food if she's asking for a snack just before a main meal or if she asks for sugary type foods and I feel she's already had a lot of sugar that day. I always offer a healthy alternative in this case.
