Caroline has decided that she doesn't like babies. I think little sister being a bit, um, high maintenance due to health issues has left her a little bored and disenchanted. When I explained that I know it's kind of a drag to have a baby sister right now, Sylvie will soon be able to crawl and laugh and play with her, and that one day Sylvie will be as big as Caroline is now and that Caroline will be SIX. And then she will always have someone to play with. All. The. Time. She started getting excited at the prospect of her little sister again.
"So, one day I'll be SIX and Sylvie is bigger, like a toddler, and then we will get another baby!"
Thankfully, she fetched the smelling salts after I fainted at the mere suggestion.
