Thanks everyone!
PW, she's almost 8 months old now, so height wise, I think she probably is. She's 24", so maybe she'll gain one more, but I doubt it. Weight wise, she has quite a bit more to go. She's 54lbs.
Angie, lol, I'm sure Dance will probably feel the same way as Phoebe someday. She's good at turning quick though & stopping abruptly, whereas Keira is not, so I think she'll always have that advantage.
