Baby mobs stay small

I know this probably sounds stupid but I just lost son yesterday. He was due march 2nd his umbilical chord was underdeveloped and wrapped around his neck 3 times. I looked forward to doing so many things with him. One of which is playing Minecraft. I want his name to live on because he can never grow up. I've seen the idea pitched to be able to name baby mobs and keep them small with the new baby mob textures. I propose naming a baby mob jasper keeps them small forever just like him.
