You have predators and recyclers in your garden already which is a fantastic sign.
Try building an insect hotel for these predators. That will hopefully concentrate them in one spot when they aren't hunting and reduce the likelihood of an accidental run in between them and your kids.
Over time, as the ecosystem becomes more complex, it will become more stable. The cricket population will drop etc.
For now, maybe you could advertise on Craigs list or something to see if there is a backyard chicken farmer who would lend you some chickens for a day. That's probably all that would be needed to cull the cricket population, and you get fertiliser in exchange.
