Well, part of their mental age could be from pokemon growing more quickly as well.

Yellow.... Your too damn cute

um continuing to snuggle regardless of age could turn real awkward real quick, especially during puberty

If Yellow's ten years old physically/mentally after two months... that translates to roughly five years a month. Blue, Red and Green would be 20-25 depending on how long it's been! No wonder Meagan can't take her eyes off their human-ish forms!

That's assuming it is directly proportional. For all we know it could be inverse, exponential, or even random

Yellow you could win the Elite Four just by mainly being cute

Please, I can't take anymore Yellow! I can feel the diabeetus!

how exactly do you pass down nano machines to your offspring I my mom had a flu vaccine that made her immune to the flu that doesnt mean I wont have it … I think

Considering MGS 1-4 i'd just say nanomachines son but how did said nanomachines transfer to the kids? Did they need a transfusion and silver donated? Did a small amount replicated and hitched a ride on the egg while it developed? Sooo many questions

To answer your question, yes if your mother is vaccinated you generally carry over those vaccines depending on how recent they were. Nanomachines would be in your mother's blood and other cells, and when you are in the womb you actually share your mother's bloodstream. This is why having certain blood types can be problematic, as your blood might actually "start a fight" with your parent's, or your parent's antibodies might view your cells as foreign and try to kill you.

Depending on your mother's history, generally they just give you vaccines as needed, but sometimes they will just give you "booster shots" instead, which are a vaccine, but slightly different as rather than giving your body enough viral or other material to recognize and prepare for an infection, they just give you a very small amount of the infectious material to make your immune system react to it. Your immune system has memory cells that "remember" certain infections, but if you don't encounter something for a few years, it eventually deletes them because it thinks you don't need it anymore. This is why some diseases are considered particularly nasty (it's also a concern with COVID-19, because some victims are experiencing this), as some like malaria, kill your memory cells and effectively cause a reset on your immune system. So if you ever get malaria or other similar diseases that do this, you'll need to get all your vaccines again, and be much more susceptible to even mild diseases like the common cold.

so basically some nano machines were caught inside the kids while they were forming and cause theyre silvers kids the nanomachines reconise this and provide the base form for them
