When my son was that age he pushed his way into the front window at a toy store and I picked him up, tucked him under my arm, and carried him sideways out of the store.

We sat down and talked about it just a few steps outside. Somebody called the police on us because an officer showed up; the three of us had a good conversation and he left.

a good idea: let's put our 2.5 yos in the overhead!
