A conversation I had with two 5 year old girls at my family picnic:
Me: L, how do you like having a little brother?
L: When he came home from the hospital, he cried all night and kept everyone awake. I can't stand him because he is so noisy.
B: Well, you are so lucky to have him because you have someone to love and take care of. I wish that I had someone to take care of.
L: Well you can take him home then!
They get along better now that he sleeps through the night.
