According to a this report, moms and dads are singing mainstream pop songs to their kids instead of traditional lullabies and nursery rhymes.

Some say they're doing it because the pop songs get stuck in their head, and they know the words better for them than old-school lullabies like "Twinkle Twinkle Little Star". The survey says the #1 pop song parents are singing is Bruno Mars' "Just the Way You Are".

So parents, what do you think? Have you found yourself singing Katy Perry, Adele, or Justin Timberlake to your kids? Maybe even a little "Baby" by Justin Bieber or 50 Cent's "In Da Club"? Or would you stick to the old classics like "Rock a Bye Baby"? OR do you split the difference and just play one of those CDs where they turn modern pop and rock songs into instrumental "lullabies"?
