Have you found any evidence yet of your contention that the increase in sick children was because of social distancing and masking?
What else would explain it? Because kids aren't getting sick with COVID.

Immunologist Deepta Bhattacharya, a professor at the University of Arizona, said RSV cases fell to very low levels in 2020, "presumably because of COVID mitigations" — a range of precautions that included social distancing, mask wearing, and widespread lockdowns during which a significant portion of the workforce began working from home.
There's a population-wide impact from skipping a year of infections, he said, since the immune system's antibody production after an RSV infection drops off fairly quickly.
Masking will not solve this problem, it will only ensure it is a crisis for longer, if anything. Not that children even wear masks properly anyway.
