Hi!! I have a five month old son and he too gets dry patches on his cheeks and sometimes on his head. My doctor told me to use cortizone 10. You can buy this over the counter at any drugstore. It works great the patches clear up over night. I put the lotion on after his bath or right before he goes to bed. It is very common for infants to get dry skin I try to only use water on his face rather then soap since infant skin is so sensitive. The dry patches will come and go but the cortizone works great. Hope this helps.
