Moms of circumcised boys..

I’m not sure how hard I should be pulling the foreskin down. The doctor told me I need to start but to do it gently. Should it retract in one day or is it something that takes days to retract? I don’t want to cause him unnecessary pain or discomfort but also don’t want it to re-stick. His circumcision was Monday. I’ve been doing the vaseline and gauze combo with each diaper change.
