I need help..

FTM needing some help please ladies.

So my son is almost 11 weeks old and over the last week or so I have noticed that this area of my sons legs are extremely dry and seems to be getting worst.

I clean with gentle wet wipes each nappy change ever 2 hours or so and put bum sudocream on in that area with his bum. I also let him lie open for a few minutes while changing his nappy. It is not bothering him and showing no sighs of pain.

But ofcause its bothering me 😔 any ideas to what this might be, what could be causing this and what I could do to make it better?

TIA 😉
