This is really good to know! SO is circ. So idk anyone to compare... My son is 13mo and his doctor said it should be retracting (starting to at least) he has a very strong curve and it's unknown if it's from the foreskin being too tight or if it's from something that could require surgery. So I am wondering how long it will take to know.
My oldest has been retractable since about age 3.5 He was in the bath pulling his foreskin back and so we washed it, but up until then I hadn't tried so I don't know really how long it was before then.
DS two's pediatrician tried to retract him at his 2 week appt and made him cry hard and bleed she felt bad, but never did that again. He is 3 and does not retract at all. I've pushed on it gently during a diaper change to see recently but it doesn't move at all. And I'm not worried about it.
DS 3 is one and has never had his penis looked at, just his balls during routine well child. I haven't seen his foreskin move at all so I don't think it's retractable yet. Nor have I attempted to see.
