with kids, the only way to behave with them is only love, this may only the way but sometimes showing a bit of anger. but this doesn't including beating them on their cheeks or on their anywhere. show their anger to them only.
i think and do beleive that, if we behave like nature then every thing will be under control. as nature reacts on situations. nature show it anger through rain, floods and many other way when it is disturbed or when it becomes excess to it. only at that time the nature reacts. similarly if we keeps our behaviour with kids then kids will groom, grow or nurture easily.
showing only one kind of behaviour may harm the kid growth and his/her whole development.
for showing differnet bahave, you first have to be different at different situation. play different role with him.
that will help a lot.
