It looks like my grandmother is about to pass away, so I need to go see her. Its about a 12 hour trip and I can't leave my baby at home, so I'm wondering if any of you have traveled with a squirrel and how to keep her warm, best way to store formula etc. I was thinking a rice bag for warmth, thermos of hot water to heat the formula and a cooler to keep it from spoiling? I would appreciate any input!
