The Schwartz's vs Magic Grandparents

So, as previously mentioned Chris and I took a trip without Sarah and she stayed with Grandma and Grandpa Schwartz.  During this short trip they managed to:
1) Get her to babble more
2) Teach her to put herself to sleep (though we're 7 min into this "nap" and I still hear here in there playing, 40 min later after intervention she's finally asleep) Yeah, she woke up 12 min later so that doesn't count as a nap.
3) Cure her of her constipation
4) Teach her to pull up to standing and then sit back down (She had quit pulling herself up for a while because she would get stuck and frustrated.)

I am slightly disappointed though that they didn't potty train her.  I mean come on, they had her for 54 hours and they often brag that Grandpa Schwartz only needs 24 hours to potty train.

By the way, someone's still teething.  Can you tell?
