Lilly, I'm afraid you are a bit misinformed.
"My husband is American, and apparently, all male children are circumcised at birth there,"
Approx 30% of baby boys are circumcised in the UK, there has been a large decline in recent years for many reasons.
"nowadays many specialists encourage parents to look into circumcision."
I'm intregued as to what country has specialists reccomending Routine Infant Circumcision. In the UK and most "1st world" countries it is not seen to have any medical or health benefits unless the child has a specific medical condition in which case circumcision is still seen as the option of last resort.
I'd be curious to find out what the process is in the UK and what is the best time to do this (eg, at birth as in the USA or some other time).
In the UK, 18 years is considered the age of responsibility, let your son decide then?
For most children it is unnecessary at any age and according to confuddleds data on page 20 the death rate is quite worrying.
Which type of circumcision method are you contemplating? I
I recommend that you watch the video for the type that you are considering, evaluate the risks, the degree of distress that it could cause either to the child or the man.
If you can't bring yourself to watch the video then don't do it and be happy that your child is perfect with a foreskin.
