You can find a lot of research out there for both sides. It's a somewhat controversial topic on these boards and it can get quite heated. IMO it's a very, very personal decision and one that you should decide with your SO.
^^^ this was very well said and very true. A good source of information would be the AAP, they have facts without trying to push you one way or the other, in my opinion. But I do believe you should share in the decision making process and not just leave it up to your DH because you don't have a penis and he does. If you are thinking one way and he is thinking another, your LO deserves you both to talk it out and make a decision together
