My four year old likes to be lazy when walking, but she'll run at the playground for hours on end. I used to bring along a strap when we'd take her tricycle to the store half a mile away so I could drag her home since she would whine about being "tired" (read: too lazy to put in the effort since I know daddy will pull me home).

For the past few months whenever I take her out of the home she now has no choice, I'm not going to bend over to pull the thing as the strap gets left at home - she's stopped being such a pill about it as time has gone on. I'm glad I did this, we're going on a trip to Boston at the start of May and she's going to have to suck it up and walk around with mom.
