Standing alone

Alexis is 10 months and just about 2 days old!  Today she stood unassisted for the first time.  We were in the kitchen.  She was standing up playing in one of the cabinets.  I handed her the sippy cup.  She reached out with one hand, realized it would take the other one too, let go of the cabinet, and stood drinking her water for about 10 seconds.  I very quietly screamed with my hands over my mouth and then got a bit teary because she looked like such a big girl.
