(Possible?) to make your own Baby Dino Mating?

I have a Idea i want to make which i think is awesome but it requires me to create a mating system for a “creature” that does not have it so basically i have models of diffrent sizes of the CREATURE and now want to use those to make a mating sstem for this Creture can anyone help me out?

I’m not completely sure, but looking at the files we have I don’t see a separate mesh for babies. Instead the animal just seems to be scaled down (with some parts being scaled down less then others)…
