Over the years I have carried a variety of bags into the parks (crossbodys, fanny packs, backpacks). However, now that my kids are getting older, I want something different. I still want to carry all of the basics into the parks (water bottle, sunscreen, migraine medication, sunglasses, fan, and of course minnie ears). My daughter is also a type 1 diabetic but for the most part she will carry her own supplies (I will have a few snacks for low blood sugar just in case). What is your favorite park bag?
