Jax doesn't even think to try the hide in the racks thing anymore.
Knock on wood, I very rarely have a problem with her anymore when we are shopping.
When going grocery shopping, she's in charge of the list and so has a focous.
When we're doing the department store thing (including Wal-Mart) things on the list for her are divided, some first and some last...........she behaves in the middle because last can be decided against.
Hardware stores and lumber yards are never a problem.........I don't know why, but we have never had a problem with her in those places.
My girls used to hide in the racks. As soon as I got one, the other one would be hiding. I hated taking them anywhere.
Then there was the Santa picture when Jeremy was I think 6, and the girls were 4. We got all dressed up to see Santa. As soon as we walked into the mall, Jenny took off outside. I couldn't get Emily & Jeremy to walk fast enough, so I just told them to stand still. Someone else caught Jenny. I don't think I took her to the mall by myself until maybe when she was 6. The following year, Dad came with us and we went to a smaller mall.
Now, I have the perfect solution to me taking them to the stores for errands. My kids are all old enough to stay in the car by themselves. We just got a new mini-van with a DVD player. I turn on the DVD, and they are happy. I don't do long errands, but I can run in a get a few things at the grocery store or go to the post office. Of course, we'll have to watch it when it gets hot outside. Jeremy's old enough to know what to do if it got too hot. He's almost 11.
