I have a 2 yr old, - does she need a passport to travel to Aruba?

No. A government issued (from the city, county or state, whichever issues them where she was born) certified copy of her birth certificate is all you need for her, no hospital ones, no Notification of Birth notice. Gotta be the real thing.

Mark. Our now 5 year old grandson has been traveling with us to Aruba since he was 11 mos. old. We figured that a passport was the easiest way to go as it has all the pertinent info, along with his picture.No shuffling papers to check in aor at the gates. With all the added security nowadays, it makes it a lot easier. Plus, it is good ID wherever we take him often, i.e Canada, etc. John
