My mom always told me that she would tell me when I was little and starting to whine that she couldn't understand whining. I filed that away in my mommy filing cabinet and hoped I wouldn't have to use it much. Sadly the last few days my son has started in on the whining and huge crocodile tears whenever something is going differently than how he would like it to be.
Luckily for me, the "I can't hear whining, sweetie." approach seems to be slowly making its impression. I am also fortunate to have a husband willing to present a united front on the subject. I had already dealt with the occasional yelling with "yelling hurts Mommy's ears" or "Yelling scares your brother," which is usually true. He doesn't like the idea of making his brother cry, so this can be effective.
I just hope for my patience's sake that he will revert to his normal, happy-go-lucky self soon. His particular brand of whining and fake crying really grates on me.
