Some parents are riled up over a new "Breast Milk Baby" doll that allows children to imitate breast feeding.

Each doll comes with a special halter top to be worn by the child. The garment has two flowers positioned where the nipples would be. When the doll comes in contact with a sensor in the flowers, it moves and makes sucking noises. The doll also cries and can be burped.

"Breast Milk Baby" was first made in Spain by Berjuan Toys. Now the company wants to debut the toys in the U.S. market.

However, some feel the toy is disturbing and unnecessary.

"I just want the kids to be kids and this kind of stuff, we don't need it," said conservative commentator Bill O'Reilly.

But Berjuan Toys U.S. spokesman Dennis Lewis says the doll is useful in teaching nurturing skills.

"A little girl who plays with a breast milk baby now will think breastfeeding is the normal way to feed a baby," Lewis said.

Still, critics feel the doll sends the wrong message.

"Children have played 'parent' with dolls for centuries, but this new twist seems to focus not on what babies are like as much as jump-starting a focus on breast-feeding," psychologist Jay Reeve, CEO of the Apalachee Center, told ABC News.

"I'm always a little disturbed by toys, games, or products that have the impact of accelerating childhood identification with being a full-blown adult," he said.

Berjuan Toys says the doll has been popular among young girls and is targeted to kids ages two and older.
