If I remember it's usually double the eight week weight plus a pound or so to be on the safe side. As always it's can be an iffy thing because you can get a baby that just blossoms with a growth spurt. When I got Lex at 14 weeks he weighed about 3 lbs and now at eighteen months he is a whopping 9 1/2 lbs.
