I do not think the same rules apply in caring for intact and circumcised children.
First I will explain that (you probably know this by now) the intact foreskin is fused to the surface of the glans at birth. But it's not actually attached to the glans- there is a membrane called they synechia that bonds the two surfaces together. the synechea gradually breaks down and the two surfaces, when they have the maturity and hormones to support this, will become seperate and able to exist ajacent but unattached to eachother.
When parents of intact boys are old to not forcefully retract- part of what they are protecting is this layer of synechia from being disturbed or torn.
If the synechia is torn before the body is ready, the surface of the glans and the skin touching it may grow attached to eachother in the body's effort to heal itself.
When an infant is circumcised, the synechia is torn as the first step in inserting the circumcision tools past the corona of the glans. If enough skin is left (or enough pubic fat pushes skin forward) skin touching the immature surface of the glans may become re-adhered. This is very common, much more common in the first months after a circumcision, but for some children this can contine for several years- it seems that if adhesions keep getting torn over and over- the glans stays raw and keeps clinging back to anything touching it. If you aren't dealing with adhesions, you are probably out of the woods with that. There are mixed medical opinions about how best to treat adhesions... I can't offer advice on that but I do advocate for consent/information and anesthesia before anything is ever done. Seems many moms and babies are hit by a "sneak attack" when the adhesions are discoverd and torn apart in one fell swoop infront of thier disbelieving shocked faces.
What not such a grey area is in regards to adhesions involving the scar line as scars tend to run amok when forming adhesions and will grow beyond attached and go into the surface of the glans. These result in what is called "skin bridges" in an adult. You could look up a picture gallery of skin bridges at circumstitions.com (but you probably shouldn't) Anyway- ev en thought you haven't said that you even are dealing with adhesions- I'm just bringing it up because the presence of scar tissue in the equation is the reason why the care for intact and circumcised babies is different. Retracting intact babies can cause scar tissue that makes problems... retracting circumcised babies can prevent the scar tissue of the circumcision from causing problems.
I hope that was clear and helpful. Gentle rinsing in the bath is all that's needed- no soap as that can be irritating to genital tissue.
