Getting bigger certinaly is not going to hurt. But nursing at the breast is what will help a baby get the hang of nursing sooner. Babies learn to nurse by nursing. I am not suggesting there is anything wrong with rapid gain, or that anything should be restricted. I guess I am wondering if it might be fine for gain to be a little slower -more average-at this point if that is the price of babies being encouraged to nurse more.I know their wt gain is very rapid but I don't want to restrict them especially if getting bigger will help them get the hang of nursing sooner.
