How can i keep my kids healthy during the summer?

Food and play: Most children are healthier during the summer because they are out of school, relaxed, and playing. Diet is #1. Feeding as much fresh food as you can. As much organic as you can afford. Fruits and berries help boost the immune system as well. Elderberry twice a week is a good preventative. Drinking water to stay hydrated. Also have their vit d levels checked. Level of 50-70 is desired.
