I have also read many times that it is uncommon for a child to self wean before 2, although it does happen as we all know children are all different. I think the definition of "self weaning" is a little unclear, and that's where the confusion lies. To me it would mean that the child has lost interest for no other reason than self interest. Things like supplementing, supply issues and other health issues can prompt a child to lose interest but I wouldn't consider that self weaning since it was a combination of things that prompted the weaning (not that that is bad in any way, I'm just talking purely for the definition of "self weaning" and the statistics of when it happens). I think that's why the statistics seem alarming to some.
Anywho, DD went through a phase of not being so interested, but she always came around. There for a while she would basically do gymnastics while she was nursing and I just thought "isn't nursing enough, do you really need to be kicking you feet, tugging at my hair and wiggling all over the place?!!" but she settled down. This was right around the time she started crawling.
I would give it time, if she is ready then it is awesome that she is the one that gets to decide and that you are following her lead. But like I said, it could very well be a phase that will pass. I'm hoping things turn out wonderfully for the both of you! I have followed your struggles and triumphs and you are an amazing mother, no doubt about it!! Please keep us updated!
