Many moms are taking rocking your baby to sleep literally. A new study found that more moms are singing pop and rock tunes to baby than traditional lullabies. Out of 2,000 mothers polled, two-third preferred to rock out with their tots before nap time. Thirteen percent of moms thought lullabies were too old fashioned and 10 percent couldn’t remember the lyrics.

The top 5 baby hits are:

1. Patience – Take That (yes, it was a UK study)

2. Angels – Robbie Williams

3. I Kissed a Girl – Kate Perry (just plain weird)

4. You’re Beautiful – James Blunt

5. Love Me Tender – Elvis Presley

(Guns n’ Roses even made it in to the top 10 with Sweet Child O’ Mine)

While I’m still a fan of the classics – I sing a mean Wheel’s on the Bus – I can be found singing the occasional pop tune. For months after my first son Bode was born we used to dance around the house to Justin Timberlake’s Sexy Back (changing the words to “Bode’s bringing preppy back.”)

I’m all for mixing the classic baby tunes with some new pop hits.

What are your favorite tunes to share with baby?

With my first baby, I was all about attachment parenting–when he cried I picked him up (immediately), I breast fed on demand, we spent hours a day cuddling and he fell asleep on me often. So one of my biggest worries when my second son was taken to NICU less than an hour after birth was: How will life in an incubator, with limited human touch (and no hugs from mom), affect my child in the long run?

Obviously I was excited to hear the results of a new study published in Psychiatry Research. The University of Montreal study followed 1,212 children through adulthood and found that newborns who spent time in an incubator are two to three times less likely to be depressed when they grow up. The researchers’ original hypothesis, like my own, was that early mother-baby separation could result in heightened rates of clinical depression later in life.

Why were the results so much different than expected?

Researchers aren’t sure, but it could be that incubators are controlled environments where body temperature, brain oxygenation, sound and light are adjusted to maximize neuronal development. Or, maybe we just make up for lost time after our little ones are released from NICU.

Whatever the reason, this study can help take a little stress out of a highly emotional time for moms with babies in the NICU.
