When in 2012 was she born?
My hypo is just about 1 year old and approaching 900g. My lesser that i got at the exact same time is 500ish grams. My hypo just eats more.

Imo, you're not over feeding. Im sure some will disagree though. My opinion is: if they're hungry they'll eat, and if they aren't hungry, we all know darn well they won't eat lol.
