Frozen 100% fruit bars from Power of Fruit

These will be great once the twins grow some molars. Like the package from Power of Fruit says, all it contains is 'fruit, whole fruit and nothing but fruit.'

The fruits are not pureed and the twins are not doing well with a mixture of textures and sizes yet. Some of the bigger pieces they try to spit out and everything comes out. I tried mixing it with some baby muesli but still no luck.
