I have a feeling we will be going to the zoo many times this summer. On our way down, Charlie made animal sounds and I tried to guess what he was (until he fell asleep). We started at the gorillas and I think we could have spent all morning there. We named the big silverback "Big Daddy".
Charlie did quite a bit of walking on his own. When he was tired he really didn't want to get back in the stroller, but wanted me to carry him. I explained he was too heavy. Now sometimes when I do carry him he tells me he is "too big for mommy". I tell him that he is growing up fast, but he will never be too big for mommy.
