Our son is almost 6 and if I want him to do something quickly I will tell him that I will count to 5 and he needs to have done it by then.
I'm sure lots of you do this as well.
The good thing is, he always does it before I get to 5.
The weird thing is because he always does it on time, I have no idea what I would do if he didn't manage it!
At what age does this trick stop working ?
