My son is 17 months, uncircumcized and has never had a problem. My 5 year old nephew is also uncircumcized and has never had a problem. I am pregnant with boy #2 and won't have him circumcized either.
My OB when I was PG with my son asked us if we were planning to circumcize, and when I said no, she said "good, then you don't get the lecture". She saw no medical reason to have the procedure done.
I encourage you to do what feels right to you and your husband, and disregard family members who don't understand or think it is a bad decision. My mother-in-law is a nurse at Childrens and ALL I HEARD about the first few months was how many problems we were going to have with our son because he isn't circumcized. She works in the out-patient clinic for day surgery and I swear the way she told it every boy that she took care of was having a circumcizion... her way of telling us we were making a mistake by not having our son circumcized. I am so glad that we didn't cave in to her pressure to have it done because so far we have never had a problem, and I am not worried about it. Our pediatrician is also supportive of our choice. MOST of men in the world are uncircumcized... the way I see it, that's the way they are born, it seems like how they are supposed to be.
