Subs on restarts?

[ref47]

for kids games we still use unlimited subs at throw-ins (some leagues possession only, some both teams if possession team subs), goal kicks, ko. our state cup matches (15 and up) have gone to any stoppage but limit subs to 7 per half or ot. once out in a half = cannot return until next half. doing any stoppage without limit on number is nuts.
