I would need your help

Hello to all,

As part of a Sims 4 project I am looking for

one or more dolls in decorative object, a baby girl or boy,

lying on the back or on the belly ...

thanks in advance

Note :

Here is an example of what I would have liked

but there it only has for Sims 2 and I am unable to make converts,

nor even if it is feasible
