Breastfeeding: How Old is Too Old?

I'm starting to realize just how taboo this topic is, because I haven't been able to find a lot of reliable and accurate data on American mothers and their breastfeeding habits. But what I have found is generally this:

60-70% of American mothers breastfeed their children while still in the hospital

25-40% of American mothers breastfeed their children up to 6 months

less than 5% of American mothers breastfeed their children at 18 months

So what happens when mothers are breastfeeding past 2 years old? What about 3 years old? What about 8 years old??



Your thoughts?
