I've got a question. My son was diagnosed with type 1 diabetes last week. We are planning on going to the park this weekend but I'm running into a few issues. There are no nutrition facts anywhere on the website to calculate his carbs. Any idea on how to figure that out? Secondly this one is more for the summer, but when we bring his insulin with us when it's hot out, how do we keep it a little colder that the outside temperature? It doesn't have to be cold just at a room temperature.
