That's about how far along I was in my PG when DS weaned. He just didn't like it anymore. He'd go in and then stop right before the nipple and then back away and sign for the other side. Then he'd do it at that side, too. He was preverbal, but it must have been some sort of smell or memory of a new taste??? Well, I was ok with him weaning, especially, since there was a new baby on the way and he didn't seem in the least bit upset with not nursing. After one time of not liking it, he never even asked again.

What happens next is somewhat up to you. You can accept her weaning or treat it like a nursing strike.
