Query: Very disappointing!

I purchased this backpack b/c we have a 16 month old and a newborn. We used the packpack for 2 months and the mesh is pulling apart, I've mended it several times! It is just not holding up well at all. Also, it doesn't hold nearly what I expected. The only good feature is the insulated food compartment.
