You know how that slow, New Age-y instrumental music that spas play can make you feel sooo relaxed? (Not that you've been to a spa lately!) Download similar tunes onto your iPod or smartphone so you can channel some Zen during your daily commute, while you're running errands or even when your babe's screams are enough to make you cry. Doing dreaded chores? Crank up something with a faster beat and sing along. (We're partial to the music of fellow new mom Pink.) You'll feel better, we promise!
