her little mind

I was talking to Katelyn about the new baby the other evening.  She's been through a pregnancy with me before, she's heard all the talk about a little baby brother coming.  I'm curious how her little mind works.  So I said "you know Katelyn, when baby is born he's going to come home and live with us.  Won't that be exciting?"  She said "no, baby come out but he not come home".  I wonder if that's what her little mind thinks.  After all, that is what happened last time.
