9 month old with a yeast infection

🐘🐘🐘 • 👧🏼 born 1/19/16. 👼🏼 lost 9/15/17. 👼🏼 lost 11/26/17.
I took her to urgent care on Friday because her vagina was red and swollen. They prescribed her some cream and cough syrup (she's got a cold too, poor kid). It's Sunday night now, the affected skin is really dry and peeling like a sun burn. Should I follow up with her pediatrician tomorrow?
