A number of people have asked me how I go to the grocery store with all four.
Here's how we roll:
Ella actually walks but on the way out she wanted to hop in the cart once we were bagged up. I end up with a couple open boxes at the checkout but it's worth it to have occupied kids. The major hazard is the candy display at the checkout. I wait back with the cart until we're clear to go through to the bagger and we zip past faster than little hands can grab M&M's.
The Christmas wrapping paper was 80% off!
