Mother of girls here, but sharing my friend's experience.
She came to the UK with two US-born boys, both circ'd. Got pregnant with boy #3 and paid privately to have him circumcised here in Oxford. She said that she regrets it, because she a) didn't like that they had to wait til baby was 10 days old, and it seemed much harder on him than it was on the first two, and b) she got a sense that the doctor was just not as experienced and the procedure itself did not turn out well. (They are back in the States now and their pedi is suggesting a wait-and-watch approach, but has let her know that it might need to be revised at some point in the future.)
Just my £.02.
