Best of luck with your family! I still believe Mr. Baldy is bald because:
The skin at the top is darkened as a shadow similar to the area beside his cheek creating depth as the light source is directly on the face.
The same thing is done with Mr. Mohawk for the balded parts outside of the hair. We all do have our different opinions though and I can see how it looks like the close-shaven crew cut.
Little rare Lilella in your second generation is such a cute surprise!
Technically the best couple for colored hair would be Rainbow and Spike since only the colored hair is part of their natural genetics. The other couples are also great though

Looks like my current generation has given me another rare child
