We babysat my friend's two little boys Monday night while she was having her baby. Tuesday morning she came by (with her husband) to pick them up and brought her one-day-old daughter. And I got to hold her!!!!
My 4-year-old was sitting on the couch between us and he looked from the baby to my friend to the baby to my friend and back and forth for a bit. Then he looked at me with great confusion, "If _____'s baby is out, why is her tummy still fat?"
He looks at me and continues, "Are you SURE you don't have a baby sister in your tummy, mom? You're fat too."
