Q: Can a 4 year old open the thermal by themselves?

Yes! My son is 4 and he opens his on his own. I thought it would be a struggle, but we practiced and he got it on his first try. I wouldn't close the lid extremely tight, but he does just fine. I would still practice with your child just in case.
