the only-child blues

"Mommy, can I have a sister?"
It's not the first time he's asked, but it's also still a surprise when I hear those words. Saturday, he wanted to get one at the fair. I told him we could get a lot of things at the fair, but a sister wasn't one of them.
Fortunately, Daniel is easily distracted. But the question remains: What's best for him - only child, one of two, or one in a a full house? My vote: whichever makes mom and dad happy. The kid will adjust.
