I have an issue with the title. As for nursing until 3-4yo...I have zero issue with. I may nurse my daughter that long. I find your first post, NBP, offensive and it comes across as quite ignorant. There is nutritive value. Moms don't nurse into toddler years for their own benefit only. The natural weaning age of children is actually closer to 4yo. All this I know because I've researched breastfeeding for the past 3 years now. But what do I know....
