I would imagine it's fine as long as your not going to get bumped r drunk lol x
The baby will hear the concert, and hear it loudly if it is loud. Talk to your doctor about whether it is advisable. I would tend to suggest you not do it simply because should the baby be born with a hearing issue, you never want to wonder if it was that time you went to the concert. In short, it might not hurt, but if the baby came up with something later would you want to wonder all the rest of your life?
I'd think it would be OK if you're not to close to the speakers baby will probably move around a lot
It's fine. I went to heavy metal concerts at about 7 months pregnant with each pregnancy. No hearing issues. We sat fairly close to the stage each time too.
