The rule is to take their weight at 8 weeks and multiply it by 3 or at 12 weeks multiply the weight by two. Of course this is not always accurate. They have growth charts too that you can go by, but again there is no way to tell for sure how big they really will get. Your baby will more than likely be pretty small, my guess would be around 3.5-4 pounds but she may not even get that big. |
