I saw Pearl Jam & Kings Of Leon when I was 6 months pregnant with Harrison... he loved it and would kick me hard when the music stopped.
I will be 7 months pregnant when I go to see Pink in July, and I just went the other night to see The Veronicas. Pregnancy won't stop me from going to concerts and each time my midwife/s have told me to go ahead & have fun but to keep hydrated.

I hope you have a great time at the concert
