I got an update from Lori at Real Hope for Haiti, where Alex is:
height 23.5 inches
weight: 12 pounds 13 ounces
wearing 3-6 month clothes

I guessed that he was smaller than this and will have to return the diapers I bought and get some bigger clothes. Most of what was donated was 0-3 months.

His paperwork should be getting to Haiti next week for his visa!
