I've never seen any writings that really address this in depth, only that those boys who have loose circumcisions and thus the foreskin remnant covers the glans will have the expected appearance of a circumcised penis at around 3 to 4 years old when the penis grows.
The big danger here is that by "tightening up" the circumcision, the child could easily end up with a genuine case of buried penis syndrome that will require skin grafts to resolve and will leave horrible scars on the penis. This happens when the connecting tissue that anchors the penile structure to the pubic mound is cut short and reattached higher up on the penis, pulling the penis into the pubic mound.
There is also the danger of the skin sleeve being cut too short resulting in painful erections as an adult.
