Another sister

A few days ago Emmett said to me, "Mom, since we're going to have another brother, then we need another sister too!" "We'll have to see about that!"

Then, this weekend I overheard this conversation.

Emmett: Dad, we're going to have another brother, we need another sister too.

Eric: I don't know, do you think we could handle another Eisley?

Emmett: No, not another Eisley, a different girl.

Eric: I don't know if I can handle another girl!

Emmett: But mom can!
