On the walk back from P's bus stop today, a woman stopped us and asked the girls if they had a baby brother or sister (she was in the sling). Since explaining the dynamics of our little foursome is...complicated...we all just replied, "Sister."
Just now, while playing upstairs, that exchange must have still been lingering on S's mind, as she asked me, "Who is Ava's big sister?"
"She doesn't have a big sister," I said, "but maybe if I have another baby someday she'll have a little baby brother or sister and BE a big sister!"
"When you get rid of that baby?" she asked.
Hahaha. I tried to explain to her that you don't 'get rid' of babies, but rather they grow up into big girls and boys, but I'm still pretty sure she's under the impression that ill someday get rid of Ava in exchange for a big girl and a 'new' baby. Hilarious.
