Query: flimsy and dangerous

I think many of the positive reviews are coming from parents with calm, docile babies, or parents who have not used this play yard system more than 2 months.My son is only 8 months, but very mobile. He pulls to stand and regardless of the shape or orientation of the play yard he can easily tip it over. Square, hexagon, rectangle, he can flip it. Plus, it is VERY difficult to open. It's barely possible to open with just one person let alone one handed. No one-handed option. Today, I tried to reconfigure it into yet another shape to see if that would minimize flipping and CRACK, I broke off a piece of the connecting hinges. And yes, they are sharp. This product is poorly designed, and frankly a stupid item. It's a total waste of money.
