Even on the most rainy days, sometimes my kids want to play outside. As long as there's no thunder or lightening, they play. They play sports, run and jump in puddles, find treasures in the yard and make up new games.
It's also nice to find some cover and read a book or watch a movie, but, I feel like there is something about summer rain that makes kids want to get out and get drenched. Are your kids the same way?
