My little boy was 9 ounces at 8 weeks, and 1 pound 7 ounces at 3 months. so he really grew during this time period. He is now over a year (continued growing up to the year, but some stop as early as 6 months and I think most stop at 9 or 10 months) and weighs 3 pounds 14 ounces so he weighs more than the growth charts predicted and more than 3 months doubled. It really doesn't matter what the parent's weigh. His parents were 3 and 1/2 pounds and 4 pounds. It's more what's in their background. If the parents have had previous litters that would be your best approximation. If yours doesn't grow much in the next 3 weeks he will probably be around 3 1/2 to 4 pounds, but he could easily reach his parent's size. My best guess would be 5 pounds. |
