The baby sure looks . . . different. Appears like she wears a wig, is Asian, and a lot older than a baby 3 or 4 months. No wonder they kept her hidden. If I had to make a bet, I'd say it's not their child.
I'm trying to figure what nationality. Mixture of Japanese and Caucasian?????
When they had Suri's Birth certificate made up they did it because she supposedly needed a passport. For a child who has been holed up in the "compound" her whole life, why would she need a passport?
Babies can be born with a full head of hair. Unfortunately at about 5 months they lose the hair (hormonal thing) and look like Humpty Dumpty. If they are teething and drooling and bald they're not very attractive - except to the mother.
