There are several things here. Some were brought up in your responses...
First thing, breastfeeding: It is not only uncommon but also generally not accepted to breastfeed beyond toddler years.
Second thing, fondling: I find that entirely unacceptable. YES, I get it, it is a source of food for babies... BUT it is also sexual, and private separately from using it for feeding. It just IS. Why else would a guy get immediately turned on by sight of a nice pair? Also, to be totally frank, a woman gets turned on by breast/nipple fondling. It isn't an opinion it is a natural fact.
If my children touch me or someone where they shouldn't (I'm not talking about sitting on my lap and resting their head, I mean hand on breast touch, etc) I calmly (but firmly) say, "No, that is private" (I have four girls).
Third: That stupid TIME cover. It is inappropriate not because that child is older but because it is using her breast and her child for attention. It is absolutely unacceptable. The breast serves more than one purpose, and we can't pretend it doesn't. Also, putting it on a world-wide cover is only exploiting something that is supposed to be an intimate bond between mother and child.
Fourth, "Mothers love": Us moms love all over the place with our kids, we don't need to show it in controversial ways. I'm worn out at the end of each day about how much love I show through all I do as a mom! LOL!
I'm not knocking extended breastfeeding, at all. I will admit that if it is beyond toddler years I find it more than weird- mainly because it isn't necessary, so it causes people to wonder, "why?".
I breastfed all my four girls.
