Funny timing that this thread is on the first page. I was randomly thinking about this thread the other day and how none of our friends are breastfeeding anymore by our age (mid-40s).
That was until last night when my wife's friend said they are having a second kid. They are mid-40s. And while on a FaceTime call, I heard her tell my wife that "at my age if I am still able to breastfeed, then I am going to do it anywhere, anytime, own it and let everyone see it, by golly." (Yes, she actually says "by golly.")
I will update you in the future if she sticks to her word.
