weight gain during pregnancy too high?

Saw an interesting article today that leads me to question the weight gain recommendations. The Harvard study looked at weight gain in women during pregnancy and the risk of the child becoming overweight. They found that women who gained the recommended amount of weight were four times more likely to have a child who was overweight at age 3, as women who gained less than the advised amount. The women who gained too much weight during pregnancy were also at a higher risk of having an overweight child.

Since really taking off the baby fat begins during pregnancy, I've always told pregnant women to make sure not to gain more than the recommended 25-35 pounds; or if overweight to begin with, 15-25 pounds. But this new study, calls into question whether those amounts should be lower, at least for the sake of keeping your baby at a healthy weight (and it would make taking off the baby fat easier post-delivery). One study is not the be all and end all, but it's worth considering.
