An organized lunch bag is easier for everyone. Put the lunch box flat at the bottom, place the water bottle securely beside it, and keep napkins or utensils in a small outside pocket.
Pack in the order it will be used
Keep the items your child reaches for first near the top. Leave a little space so the bag closes without pressure, then add a reusable ice pack if the product and food require one.
At the end of the day, return every item to the same place. A consistent layout makes the next morning feel ready before it begins.
