My 3yr old boy is always crying and whining? Need advice?

Quit responding to him.

When he whines, say "I don't understand that noise. You want something, talk like a big boy". Then turn your back and walk away.

When he wants something his sister has, say "If you want berries ask me politely. Talk like a big boy".

Before you allow him to play games, sit him down and tell him that if he throws the controler, screams or whines, game time is over. If he can't play properly, he won't play at all.

FOLLOW THROUGH.

The second he whines or throws it, take it. Put him in his room. Tell him he can have another chance later (an hour, the next day - whatever you think is right)

The second he talks properly, bend down, smile into his eyes and tell him how much you like it when he talks like a big boy.


HINT:
This is new to him, so he many not know exactly what to say.

If he doesn't immediately respond with "big boy talk"...TELL HIM what to say.
Example: The berries.
Say: "If you want berries, ask me politely".
Wait a second - if he doesn't respond
Say: "Mommy, please may I have some berries".
Make him repeat the words - then give him berries.
