Hi K.,
I'm the type of mom who researches almost everything before making decisions...I feed my daughter organic food, give her fish oil supplements, buy her bleach-free/safe dye jammies, etc.
That being said, my husband and I LOVE to go to concerts together and we saw the Vines when I was 7 months pregnant. It was awesome and I had a great time. Sierra kicked a bunch inside me, but it could also have been due to the fact that I was dancing:) Before we went my mom said, "babies don't like the new rock music," which only annoyed me (I'm hardly young - my hubby and I are almost 40) But, I couldn't find anything concrete to suggest that I not go.
We bought a ex-tra small Vines t-shirt for the baby and now we've gotten into a habit of buying our daughter a t-shirt whenever we go to a concert...she has quite the collection now: White Stripes, Beck, Black Crows, and more. Have a great time.
