I bought some organic non ichy soap n use coco butter to stop the itching
Try either Sarna sensitive or Sarna menthol. They've helped me tremendously and I have PUPPP. Oatmeal baths dnt work for me at all. You might even try soaking in Epsom salts then rubbing the sarna on the belly.
Try not to scratch what ive used with all my children is anything outmeal. When your itchy take a oatmeal bayh in,warm water not hot because hot water drys your skin. I uses baby johnson in johnson oatmeal lotion it helps too. I habe 6 kids and hardly any stretch marks at all. None on my bell at all just a couple of light ones on my sides.
Don't scratch you will get stretch marks. I use vitamin e ointment and it works
I have heard co co butter or shea butter
