We bought the penguin backpack for our son's 3rd birthday. He is big for his age, but it still fits him well. Now, at almost four years old, he still likes to wear it.

The problem we have is that it sometimes falls off his shoulders. It doesn't seem very secure. I think a single strap across the chest or waist would make a big difference. We don't put a lot in the bag itself since a toddler is carrying it around, but I think if we were to weigh it down any more, it would fall off even more often.

It is very cute and he gets compliments whenever he wears it. We're thinking about getting another one for his little sister!

We can usually fit plenty in it for his needs- a pad of paper, crayons, a couple of books, and some snacks or small toys. We have used it as an overnight bag when he went camping. We were able to fit his toothbrush, toothpaste, a couple of diapers, pajamas, extra clothes, and his small crocheted blanket.

I don't think it would really work for an actual school environment. It isn't really made for heavy items like books or a school lunch. When our son reaches school-age, we will buy him a different backpack.
