We have daycare at a couple of stores, here too! Can I tell you how much I LOVE not having to pull the two of them apart or stop them from running down the aisle or climbing all over the checkout counter? They don't really ask for much, other than healthy things, so I can't complain about that. A 45 minute shopping trip will easily turn into two hours with the two of them.
We also have a delivery service now, which is awesome for times like now, when Mighty mouse is sick and it's raining and cold. Love, love, love it!
Hope you feel better.
