I imagine every single pageant mother that isn't on this show behaves in the same awful fashion. The problem is that TLC is rewarding them for their behavior.
I can't see her having another kid. Just think about the impact that would have on her perfect figure. Much easier to just do some reconditioning with her kid to make sure she doesn't disappoint mommy again.
The trick is to put them in a drawstring sack with just the head sticking out. Just make sure it's heavy canvas or burlap so they can't claw through it.
It sounds cruel, but there's actually less chance of them hurting themselves (or you!) that way, and I find they stay calmer.
