answer:(Dis)approval can be a good natural feedback, as long as people respect you and value your approval. You could ask the offended kid what he’d like as compensation. Kids also like getting some agency/choice/influence/input. Then not only could he get some fresh Rollo, he could choose to get something he likes even more (which can also help not get them fixated on candy as currency, and get them thinking about other things they might like). I might even offer a favor which he can hoard and think about what he wants for later… though all this territory wants a bit of caution. It’s best if it can be quick and natural, and if it isn’t showing that causing an upset can lead to a bunch of attention and action that the adults wouldn’t normally do. I would avoid making the offender make a forced offering of his Rollo. I would either not get that kid another Rollo, or deduct some pieces and give them to the victim myself (probably adding at least 1 more piece to compensate for the injustice).
