What to do CanCan, some parents and/or caregivers are just bo-chap with everything and anything including their children's attitude.
It was a good thing that you got your son to move on to another station. But i hope you explain to your dear son why you did that. Sometimes, reasoning out with people with bo-chap mentality can tire you out.
If that were to happen to my child when the kid snatched the toy away from my child, i'll immediately raise my voice aloud and tell my child, "Snatching is wrong. You must ask nicely before you take anything ok." - liddat look as if i advise my child right. If i can advise my child, Y can't they !!
Kindda soft-approach to get your message directed to the kid's caregiver/parent . If they still dont't get the message, confirm case they have low EQ !
