ok the same medication doesnt work with everyone..! so same way u have to deal with kids based on their behaviour..!
plus "Abbu ko bata doongee." hmm thats workable..! its like playing bully at home..!
I think using rishwat as a tool is not very good. as the kid when becomes older, may want to continue that..
but only sparingly or in control... tell them if they behave, they will get a reward.. like chocolates or toys or something.
or the simplest of all, leave the kids to someone else to take care of..!

hehe
story telling gives u the edge.. kids like stories.. and u will also enjoy when u ask them for input..!
like a lion and a barki came face to face.. who can tell me what the bakri said to the lion..
one kid, " Bakri said.. maay maaaaay maaay"
another kid.. "Bakri said.. BHAAGOOOOOOOOOO..!!"
third kid.. "Bakri said.. tukainoe sidciue buawe"" (speaking in its own kiddie language)
lol.. this will definately help.. as long as u get a good story.. plus u will get material for some nice jokes..!
