I bought this backpack for my 15 months old daughter and they wanted to put him right. I think it fits the size of both nursery and kindergarten for children when the Minis (crib) is not brimming loaded (and thus heavy) is. It can easily fit several purely lunch boxes, fruit and a bottle - there's even an outside compartment with mesh. In the bottom of the backpack has room for a change of clothes, gloves, ballet slippers or whatever needs to be transported straight. My daughter loves and wears a backpack with pride + pleasure when their daily breakfast and afternoon snacks in there. And I find it visually and qualitatively very good. Can only recommend it and would therefore at any time take it back because there are so many beautiful designs for guys :).
