i don't know how much milu weighed at 8 weeks. i got my baby milu when she was about 22 weeks, and she was 1.7 lbs.
she is 3.1 lbs now and she is 9 months old.
she kind of stopped growing for a while when she was 7months old. she was at 2.6lbs and some people said she probably wouldn't grow anymore, but she grew over night, and suddenly, all her old cloths didn't fit her anymore.
she just got longer and taller, not rounder, she is too skinny!
(she doesn't like to eat dog food...)
