I kept Vaseline on my tummy everyday until i got bigger and then started using vitamin e oil. I've never itched except when i get out the shower and need more oil, when your itchy your skin is dry because it's stretching.
Carry around a lil travel bottle of lotion in ur pocket or purse and slather some on ur belly everytime u pee
Your Skin dries out easier when pregnant. Just use lotion or cocoa butter.
