The Cupholder

As I unbuckle the baby from her car seat, I notice that her clothes are all wet with water. No wonder she has been crying in the car the past five minutes!

Me: Sophia, why is the baby all wet?
S: Because she spilled my drink all over herself.
Me: Why did the baby have your drink?
S: Because I was going to pass it to Thalia.
Me: Were you using the baby as a cupholder?
S: Yes.
Me: Please don't use the baby as a cupholder.
S: OK.
