Children often have a way of coming up with a name for the baby. I
think it makes them feel a part of the whole scene. A niece begged me
to name my first daughter Big Bird. A friend's daughter choose
broccoli for the new baby. It's cute in utero, but allowing it to
continue will only result in your child being named Billy Boo boo
Belly - or Boo Boo for short!
