Em: When baby brother comes home from the hospital, I will push him in the swing on the play set.
Mom: Oh, baby brother won't be able to swing on the play set for a while.
Em: Why not?
Mom: When baby brother comes home, he will be very small. He won't be able to do much except cry, eat, sleep and poop.
Em: That's it?
How small will he be anyway?
Mom demonstrates how small & says: He will be very fragile. That means we have to be extra careful with him.
Em: Oh, like a Christmas ornament?
