I was worried how the 2yo would do. He loves strawberries, so I figured he'd probably spend most of his time eating them...but he actually did pick a few berries for our basket. And our 7yo son is the perfect berry picker, in my opinion. He does not like strawberries (actually, I think he'd love them if he gave them a chance...) so all the perfect berries that he found went right into our berry basket :).
We ended up with 8 quarts of fresh-picked berries. We've been snacking on them and also making them into homemade freezer jam.
