Are those credit card swipe machines kid magnets or WHAT? Hillarie’s onto something:
My son is three and loves to "help" when I am trying to pay for the groceries. His help consists of pushing the debit/credit card machine and many times his help causes me to have to re-swipe the card, etc.
I will be getting him his own "machine" — a colorful calculator. I will keep this in my bag and anytime we check out he can add up the groceries himself and check us out. I can test this out first but I do think this will work well. At least for a while.
