Finally got through the entire thread! It's been very interesting reading everyone's viewpoints and even more interesting that there's been no nastiness!
I am in agreement with the majority here. When I first saw the picture my jaw dropped. I could not believe a mom would be OK with exploiting her son like that. I was disgusted and thought it was very distasteful that the mom was promoting her beliefs and cause at the expense of her son. Like a PP pointed out, what if he decides to run for office someday and these photos are unearthed, humiliating him and possibly ruining his chances at election?
I was less disturbed by the length of time the mom BFs. I don't understand breastfeeding after the age of 2 and think that there is no good reason for it after the age of 2 other than comfort for the child and the mother. Even then, I think it should be done at naptimes or bedtimes, not whenever the child feels like it. If the child can ask for it, then it's time to stop.
My SIL breastfed her oldest, H, until she was 5. She had baby #2 when H was almost 5 and breastfed both of them, sometimes at the same time. To say that wasn't a weird sight is an understatement. She was an emotional wreck when H said she didn't want to do it anymore because the kids in her homeschool co-op teased her about being a baby. So the 5 year old decided on her own, not the mother. Who knows how long my SIL would've let it continue if my niece hadn't wanted to stop.
H didn't nurse during naptime or bedtime only, it was anytime during the day that she wanted it. I remember a few times when we were there for dinner and H (4 at the time) didn't want to eat what was served, so my SIL nursed her instead. There were even times after the baby was born when my SIL would ask H if she wanted some "loving time," which were their code words for nursing. Honestly, DH and I tried to be understanding and non-judgemental, but it was just plain weird and in my opinion, not normal. My SIL was definitely doing it for her benefit, not my niece's. Her 2nd daughter is 20 months and my SIL has told me that she does not plan to stop, no matter what the age, until it's the right time for both of them. Both of them?
There was a blurb on MSN last week or the week before about Salma Hayek being addicted to breastfeeding. It made me wonder if some mothers (not all) who BF past the age of 3 and with no limits to it (like at home only, during naptime/bedtime) could possibly be addicted. There are many other ways to cuddle with your child, comfort them and show love. Nursing preschoolers, IMO, is just not an age appropriate way to do that.
