"is it easy to make a crying child laugh?"

No, Its not... God.. they yell and scream so loud... they'll not even you hear you... unless you show them candies.. make faces.. play with a toy.. cry like them.. in other words being like them.. you can't get their attenttion :). inspite of all these... i love children. :)

i think it is the most difficult thing to do!

yes i think it not so difficult to make a crying child laugh..just need temper to make it

i think it depends on the child. a lot of children forget after a few minutes why they were crying in the first place, so it's easy to make them laugh. i remember when one of my cousins was a little baby, he would always cry...so what i would do was pretend that i was crying too. that would make him stop crying to see why i was crying, and he'd try to move my hands from my eyes to wipe away my tears. it was soooo cute.

No it's very defficult.

I find that it is easy because for the children everything is new and funny!
