My 21mo DS loves the bananas. They are not banana chips, which are loaded with fat, but just freeze-dried bananas. He also loves the raspberries, strawberries, cherries and such, but the darker fruits are sooooo messy for them to eat! Peas are also one of his favorites, believe it or not - he can eat them like cereal!
I'd also caution against buying more than you can consume in a short time period (1-2 months) as they get sticky and soft, even if left in the sealed package. Supposedly throwing them in the freezer helps that, but my freezer is already full!
We have also ordered freeze-dried fruits from honeyville grain - the strawberries, raspberries, apples and peas were all hits here. Their bananas, however, are the fat-laden chips. They have cheap shipping no matter the size of your order and IMO the product keeps better, even once the packages are opened.
