In one of the u/s I had it looked like his chin would look like mine. I don't know the technical term for it, but here is a picture of a chin off google that looks like mine. I know it's nicknamed "butt chin" but I don't know the true term.
Here is the u/s photo I am referring to. I know if you zoom in you can see it.
It does look like he has the same kind as me but does it look like he has a chin similar to the picture above?? His daddy's chin is not the same by any means so I am almost certain it will be like mine.
