Yes, kids use up a lot of energy and so they are hungry. Their brains and bodies grow so fast, they need to be refueled throughout the day. Think of their bodies as cars. They need more fuel the harder they play needs to be refilled more often. In the summer you are using the air conditioner in that car so it also uses up more energy. They all have snacks. Your children are just like all other children.
Breakfast can be oatmeal, cereal, eggs, Bagel
Along with fresh fruit and or juice
Big glass of milk
Snack- Ants on a log Celery with peanut butter and raisins
Cheese and crackers
Fresh fruit salad (just a mixture of cut up fruit)
Cottage cheese and some fruit slices
Pretzels with mustard?
Dry cereal like Kix, Shredded wheat squares, Cherrios, Just keep some small ziploc bags with these cereals in them.
Raisins, dried cranberries, Dried apricots.
Lunch - sandwich, Tortilla wrap, Can include cheese, a nut spread, Tuna, lunch meat.
Or it can be tortellini filled with cheese topped with a fresh sauce
Grilled chicken legs (grill a ton of them and freeze them to be stored. They heat up great in the microwave).
Left over vegetable pizza.
Spring rolls with cooked chicken, lettuce or sprouts, carrots
Big glass of milk
In the refrigerator always have ziploc bags of fresh raw vegetables for the kids to snack on.
We always had Raw, carrots, celery, cucumbers, jicama, radishes, cherry tomatoes, we also know a lot of kids that love sliced red peppers, snow peas.
When I was enthusiastic I would even steam fresh green beans, our daughter loved them cold.
Our daughter was never into dips or dressings, but if your kids like dips, make your own by using low fat cottage cheese, blended with spices and herbs, or purchase pouches of ranch dressing mix, I use half of the packet so it is not to salty.
Purchase a watermelon and slice it up so you all can snack on it all day
They will eat a good lunch, wake up and need a snack.. go out and swim for a few hours with them, give them a tiny snack while you make a nice dinner.
The output of energy will require input of food afterwards.
In our car I had a bag of snacks (peanut butter or cheese crackers, goldfish, or a dried snack mix and a cooler filled with water bottles and fresh fruit and fresh vegetables. It was our daughters job to keep up with what needed to be refilled, replaces and thrown out. Your 4 year old will love having this responsibility
