One of Katelyn's favorite things to do is go grocery shopping with me. She asks me on an almost daily basis if we are going to Publix. I take her with me about 90% of the time since trying to shop and answer her zillions of questions don't really mix well together. And for the most part, Katelyn is very good in the store. She HAS to have to shopping cart that is shaped like a race car and "drives" the whole way around the store. She even makes sure the bananas are safe by putting the seat belt on them.
And she has become quite good at telling me what we need to buy. Even making her own lists to take with us.
