Learn to say "NO" sometimes to kids lalo na sa mga bagay na hindi naman dapat for them. Letting them understand that theres a limit for everything and you cant have them all at the same time . Have a habit of telling them to appreciate what they have and not asking to much . Talking them in a nice way is somewhat effective too.
