He didn't ask to nurse, and with the exception of one time, he hasn't nursed since. He talks about nursing, and often reminds me of when he used to nurse and how much he liked it. Natural weaning doesn't mean the mother does nothing, and the child gets to nurse any time, any where he so desires. Most mothers start setting limits on when and where they feel comfortable in nursing, and children reach an age when they can handle those limits. For instance, my son learned that I definately DID NOT want to nurse him at the mall when he was a rambunctious two year old.
Some mothers restrict nursings to the bed or a certain chair.
Natural weaning is not for every nursing couple, but I strongly feel that it is the best way to wean. Each family needs to be free to make the decisions that are right for that individual family.
