Any remedies??

My 17 month old had a swollen belly button for a month now the doctor said it’s probably related to her eczema which I’ve have under control.. she is constantly picking at it like constant. The hydrocortisone cream helped a little bit she’s still constantly going at it and how she is also constantly itching down there! The docotr said that it looked fine and is probably just self realization. I think it’s more then that tho bc it kept her up last night she kept scratching 😩 does anybody know any natural remedies for itching or inflammation that are safe??? Maybe coconut oil for down there??
