Seriously, I think what the issue here is that you people have serious issues with breastfeeding. If the doll made these noises with a bottle, I doubt it would bother you at all. It's this conditioning we have in our culture that somehow breasts are for sex rather than nurturing children that is the problem.
Hopefully, Rachel, seeline, Maren, etc., will step in here and tell me I'm full of shit so I can just STFU...
