As I was tucking Meghan in for bed, she nonchalantly said, "Mommy, Sophia says I'm not a baby."
Confused by the statement out of context, I inquired, "What do you mean Meghan? Do mean that Sophia is being a very nice friend to you? Or did you mean to say that Sophia thinks you are a baby?"
"Sophia is my friend. She doesn't think I'm a baby."
"Oh Megs! That is so nice. I'm so glad you have such a nice friend in Sophia."
I guess "not being a baby" is four-year old criteria for forming friendships. ;)
