No, not for that reason. I don't care about adults breastfeeding in public.
But thanks, I spend all my energy telling my daughter she is NOT getting married until she graduates from high school, and she is certainly not having children.
She can make believe, but it takes all of 10 minutes to teach a grown woman to breast feed, if she needs to be taught at all. This is just encouraging very little girls to obsess about their breasts, to de-sensitize them to having them handled and showing them in public. It's obscene. They use dolls like this for kids to show how they were MOLESTED.
I don't disagree with a girl not getting married and having children before they are older, but then why give them dolls at all? Why make dolls the coo, eat/drink, have brushable hair, can wear different clothes, etc.? It is all just part of teaching them to care for another.
Some grown women are never able to breastfeed and some think it's "gross or icky". Perhaps this doll, once people get over the "gross and icky" initial reaction would help those women.
And there are a lot of things that we do in caring (properly - no molestation) that could refute your argument about de-sensitiztion, etc.
