A new doll that mimics the act of breast feeding---- has some parents upset.

The doll is called "Breast Milk Baby" and sells for 89-bucks.

It allows children to imitate breast feeding by using a special halter top that comes with the toy.

And, get this, the doll's mouth actually moves and the baby makes motions and sounds consistent with suckling.

Critics say, the doll is over-sexualizing young girls.

But supporters say, it teaches them nuturing skills.
