Bargaining

Last week, after spending almost an entire Sunday at home, it was time to change into his pjs.

Aiden: I want the ambulance and fire engine (his 2 favorite toys)
Me: No, you have been playing the whole day, it's time for some story books
Aiden: Ambulance and fire engine!
Me: No.
Aiden: Ambulance and fire engine!
Me: No

About 3 seconds later...
Aiden: Car and bus!
