When I worked in the hospital, I saw first hand an adult who had to undergo circumcision due to chronic infection of the foreskin, and it was the most painful looking thing I've ever seen. (I saw the post-op result, not the actual procedure) I believe that more than 120 stitches were used. After that, I vowed that any male children of mine would be circumcised as an infant so they would not have to endure something like this as an adult. That said, IMO if this child is to be circumcised, do it now, rather than letting him "decide himself" as an adult. I can't believe any adult would willingly choose this.
Finally, since the doctors feel it is an individual decision with no opinion one way or other, then the parent with full custody should decide - in this case, the father.
A friend of my dad's had to undergo circumcision as an adult, in a military hospital, for the same reason you mention. He was a VERY unhappy camper for a considerable time.
My adopted son was snipped as a two-day-old infant (and if he had been my bio-kid, my hubby and I would have opted for the procedure anyway). When he was seven, he had to go into outpatient surgery for revision of a small adhesion at the circumcision site. It was no big deal - there was not even enough bleeding to warrant a gauze pad and the anesthesia was the worst part. He was apprehensive beforehand but allowed afterwards as how it had been a big fuss over nothing.
Anyhow, in the course of our discussions with the surgeon he mentioned that puberty is the major borderline as far as pain, bleeding, etc. So the anesthesia would be the major consideration for a two year old.
BTW, my grandmother forgot to get my dad circumcised (he was born at home) until he had his tonsils out around age 12. Nobody told him about the free bonus operation he was going to get -- he tells me he remembers thinking that his tonsils had awfully deep roots . . .
