Seem like the weight of the child doesn't really mean anything for future height/weight of the child, however, it does correlelate to the mother. A mom with a child with a birth weight over 9 pounds significantly increases her chances of having diabetes later in life. My MIL had my dh, and he weighed 9lbs. 4oz., and she has diabetes now. They told her at the time she had him this might be the case, but she didn't really think she would get it. It doesn't run in their family.
