Parker was not happy about wearing mittens. At all. I'm thinking he'll come around eventually if it's anything like him getting used to wearing pants, long sleeve shirts, and his hoodie were for the first couple weeks. A mommy can hope, at least.
Connar was psyched about wearing mittens and was very specific as to which ones he wanted to wear out of the three different pairs they own.
When I asked Connar which mittens out of the three pairs he wanted to wear, he told me, "Bofe of dem" (both of them), as if I was only going to give him ONE of the two mittens. He makes me laugh every day.
