Positive peer pressure

Well, I think Lily is finally potty-trained.  And I must emphasize the potty part, because she's not BM trained yet.  Baby steps, right?  We'll take what we can get at this point.  Last week at playgroup two of her friends went potty in our bathroom, and Lily wanted to go too, so I think we can thank them.   

We got Kate a toothbrush a few weeks ago, and she loves it.  She cries when we take it away. Our dentist would be so proud.  Lily is a good example and also loves to brush her teeth.  Kate has had a rash lately, and I'm wondering if she's allergic to something I ate.  Anybody know anything about that?
