I saw them in Tesco a while back - I don't really think Disney should be venturing into this area.
I don't really like giving my children "kids" food. I think you should develop childrens tastebuds at a young age rather than fob them off with bland mac'n'cheese and rice slop. My girls are 5 and 2 and their fave foods are olives or stuffed vine leaves!
I think it's a very expensive way of feeding your children too - all the more profit for Disney though I suppose....
