The Breast Doll ever?

I watch my kids play house and of course they have those little baby bottles where the liquid disapears as the baby "eats". It is natural and causes no concern for me to watch them do this. Now here is an interesting twist to playing house. A spanish toy company has come up with a doll and apron with daisy nipples for this kids to wear to mimic breast feeding. Is it wrong? Is it right? I am not sure. I breast fed all my three kids and plan once again to breast feed this one. I have watched my kids take their dolls and place them at their breast to feed. Now ,while I am pregnant my 2 yo will take one of her babies and shove them in her shirt. Then tell me she has a baby coming out. I think it is cute.
