Heading home from the zoo

Tyson: I don't want to go home. I want to stay at the zoo with my friends.
Me: I know buddy but we have to go home.
Tyson: But mooooooom! I want to stay with them for FOREVER!
Me: Well I'm glad that you like your friends so much.
Tyson: Can they come over tomorrow for a sleep over?
Me: Sleep over? When did you learn about sleep overs? And no. They can't come over tomorrow. (Although I'm sure all their mommies would love a night alone)
Tyson: How 'bout the next night?
Me: I'm sorry Tyson.
Tucker: I want a babies in your tummy.
Me: {total shock}
