6 week old - dont have much time left...

I second this. Don't vax til your comfortable w/the idea after doing some researching. I was in the same boat as you when my first born approached his 2 mo appt. I made a last minute decision to hold off vaxing after talking to my husband. My husband gave me good advice - if you don't have peace about it, don't do it. That's my advice to you. Either don't go to the appt (don't need to if you're not vaxing unless your child has something wrong that a dr needs to check) or just tell them you're holding off vaxing til you do more research.
