Toddler evolution doesn’t really matter with the Tamagotchi On

The tamagotchi On (and Meets, maybe M!x?)  features two different toddler types: low happiness toddler and high happiness toddler, determined upon evolution from the baby stage by low or high happiness. There is no significant difference if you have a low happiness toddler or high happiness toddler, but there IS a huge cosmetic difference. So really, you just need to feed, cure their cold, clean up poop, bathe, and cure their two sicknesses when they come up to care for the baby stage. What are your thoughts on this?

There's a theory that happiness levels at different evolution stages affect which traits your tama inherits, and teen body types are linked to which adult body you get.

Oh-I had my boys evolve into toddlers, so for 50 generations I’ll see if low happiness will directly affect if you get the mother or father’s genes, I’ll always marry Mametchi if the tama is a girl, and Mimitchi if the tama is a boy until September ends. I will keep happiness at only one bar.
