Before we left, I had a little chat with Kellan. I said we were just going to buy the boots and if he was extra patient, we could go get a frozen yogurt. I am not above bribery when it comes to a smooth shopping trip!
Kellan was very good about having his feet measured and trying on a few different pairs of boots before we settled on the right ones - a pair that looked like firemen's boots - and we walked over to the frozen yogurt shop. He tried to get me to take him to the nearby toy store "just to look" at the Legos (I remember using that kind of talk to con my parents). I was able to convince him the frozen yogurt was the only treat he needed.
How do you ensure a tantrum-free errand run?
