We usually go a few times a week. My daughter eats a lot of fresh fruit and I don't like to buy too much produce at once because it spoils quickly. There's a grocery store less than a mile from our house that we can go to if we need something fast, and plenty of places to stop on the way home from work. It's really hard to make long trips to the store with a 2.5 year old, so a few quick trips works out better for us.
