my baby is 21 months old, his genital area is looking like this sometimes, not all the time, but today it's looking quite large, I'm gonna take him to the pead , but any idea what can be this?

A. It looks like there is swelling into that area which is why it is looking like this huge and round so if it is happening even occasionally please don’t take it lightly have an assessment with your doctor and accordingly they’ll give you a guidance relating to the problem
