Happy 13th Month Kids

The twins are 13 months. Orli is walking, Zev is not yet, he's a little shy about standing now. He is getting better at holding onto a finger and walking that way.
Zev is talking more, all babble, but we can make out questions.
Orli is making all kinds of surprised faces, when a phone rings she makes an "o" with her mouth, her little eyebrows go up, she makes this face all the time and points. Each of them put the telephone on their shoulder and go "haaaa". Zev shouts loudly when you put the phone next to him, giving the caller an earfull. The kids wave from their stroller at everyone on the street, Zev perks up when he sees chicks and waves and says "haaaa", then Orli will say "bah-by" and wave too.
They like to hug eachother, we hope this phase lasts, they grab eachother and press their cheeks against the other's head and go "awwww". But sometimes they bite. Yesterday Zev bit Orli's finger the nanny told us, and then I saw him crawl by her and bite her leg on his way over to mommy and then he pulled himself up and bit mommy's arm as she was trying to hug him.
Today we heard each say "baloon" in their own way. Orli says "blooo" and rolls the 'l', Zev says "balee" and points the helium baloon we got from the hospital.
