You're going into a store -  and your 3 year old throws a temper tantrum? How would you handle this??? The kid falls down on the ground on purpose-  and starts SCREAMING. Non stop. How would you react? Would you pick them up and scold them? Let them stay there and "scream it out"? Pick them up and walk away? Something different? See below to see what the Mom did.

I was in the store for about 15-20 mn.

When I came out - the kid was still there, with the Mom standing over them.  20 minutes of a temper tantrum- and the Mom was cool as a cucumber. Wow. Her face just said - "Im not giving in"..... (strangely, i think the kid was thinking the same thing)
