Query: Be Careful!

Other than the one issue which I am about to tell you, I love this chair! It folds up so nicely, sleek and easy to use. But....there is a space about 1 1/2 inches between the seat and the frame of the chair, just below the tray, that my daughter gets her arm stuck in EVERY time we use it! She's a little thing but her arm gets very tightly wedged in this space and its difficult to free her! Please be careful!!! Other than this issue,which I've already brought to Graco's attention, the chair's great!
