Disciplining your children is never easy. I've got two kids and my toddler has a penchant for tantrums. So giving him a time-out, or taking away his toys when he refuses to eat his food or not put on his clothes, or making him help clean up the mess he made while he's screaming and crying isn't exactly my idea of a fun day.
However, I have noticed that it's ultimately been for his benefit. He's more respectful of other kids. He doesn't act out when we're at other people's houses and when he does, usually a look from mom and dad is enough to stop him from pursuing any crumby behavior.
