Limit amount of Children

Hello,
we have events where we want to have a limited amount of children participating.
For example, up to 10 participants, but maximum 3 of them can be children. Is this possible to do somehow, a check directly in the registration process?
Best regards
Eric

I now have set the total capacity of the event to 12
The ticket type adult to 12 and the ticket type children to 2
Now, when 11 adults have booked, there should be only one ticket be available, as there is a capacity of 12.
The overall availability for the event is calulated correctly (1)

The thing is, the ticket type plugin displays:
Capacity adult: 1 (correct)
Capacity children: 2 (wrong - only one more capacity is available)
So in registration process, the registrant can fill out for 3 tickets, and at the end he gets an error that only one ticket can be ordered.

Also in this screenshot of the ordering form, the user can select 14 tickets, but the capacity is limited to 12

My vision:
Correct display of capacity of ticket types, and, given my example above, as soon as one ticket is selected, the other ticket option will be disabled, as there is no more capacity.
