It seems I am always in a pickle trying to either find a high chair that is not a bio-hazard when we go out to eat or I am trying to cook one up on the fly if there is nothing available. Here is a diaper bag with a hard shell that easily (so they claim) transforms into a high chair...cool.
Why can I not think of these things? Genius...if you ask me.
I will write a review when I get the goods.
