Designing 'reborn dolls'

I am a fairly new Muslim and I'd like a little bit of help on something. I have a hobby called, ' reborn dolls' heres a bit of information about the ' reborn dolls':

Reborn doll. A reborn doll is a manufactured skin doll that has been transformed by an artist to resemble a human infant with as much realism as possible. The process of creating a reborn doll is referred to as reborning and the doll artists are referred to as reborners. Women, intend to use 'reborn dolls' of a way to get rid of anxiety or stress or struggle with child loss. Or to prepare for an actual real baby!

I've even heard colleges use these to prepare nurses and etc how to deal with babies? Is this hobby Haram? Could you give me advice on what I should do?
