4 teeth, and pulling up on EVERYTHING

Sure enough, #4 popped through on his 9 month birthday. I am guessing the pediatrician was right about 5 & 6, as he's drooling like a leaky faucet! I don't see anything yet though.

He is pulling up on everything - chairs, toys, his sister :) He's getting pretty good about balancing while he holds on with 1 hand and reaches for something with the other. We wonder how long it will be before he takes off on two feet? Addie was walking at 10 1/2 months, will he beat her?
