Four months ago I posted this:
" he is 6 mos. and weighs 5 lbs. He weighed 3.5 lbs. at 12 weeks. The vet says he should be up to 7 lbs. by 8 mos. But originally he told me they stop growing at 6 mos. Huh?"
Well now my Jackson is 9.5 months old. I weighed him yesterday and he weighs 6.2 pounds. So doubling the 12 week weight didn't really work and he hasn't gained weight since he was about 7 months.
