A new doll out on the market this Christmas has sparked criticism from some parents, as it needs to be breastfed.

The dolls look like most others — but they come with a little halter top – with a petal shaped design at the nipples.

There are sensors at the back of the design – which set off a suckling noise when the doll’s mouth makes contact.

Critics say the toy is too mature for children and should be taken off the market.
