It has been confusing. The authorities haven't changed their story from what I can tell and from what I read in a litany of articles I looked at - they age her at about 5 to 6, now 6 to 7. At least from what I recall reading all the nauseating stories. The only time the age changed was when Brian said she was born a couple years ago, making her just over two years old born in December. She weighs in like a 1 year old at 16 lbs (skeletal in form), deformed to a degree from being caged in and unable to stand or walk with her heels pressed upon her backside causing pressure sores. Brian has said she use to stand and walk prior to the caging last summer.
There is that picture of a blond girl on her lap, and she looks to be about 2 maybe from SG birthday party in 2008. That would be about the right age for this girl if the authorities are correct.
