I BADLY NEED HELP MGA MOMMIES!

Anyone here na nakaranas na sa baby nila ng ganitong rashes. Sa vaginal part lang sila nakakumpol and wala sa bandang pwet (which is kinda weird). Pinacheck up nanamin sya and sabi ng pedia diaper rash daw. Tinry nanamin lahat ng advice from the pedia. Nakapanty nalang sya pag umaga and Nagdidiaper sya all night. 3 na cream na natry namin (1 prescribed by pedia, 1 is mustella and 1 is drapolene) and walang nagwowork kahit isa 😓 At this point I don’t know what to do anymore. Sa mga mommies na nakaranas na ng ganito and have some advice, please help me. (8 months pa lang baby ko)
