I always recommend earth mama angel baby bottom balm, but a week ago LO's rash became really bad and I knew I had to try something stronger. I tried milk of magnesia & Desitin maximum strength and it really seemed to dry up the rash and stop it from spreading, but after about a week, her diaper area seems a bit sore, maybe from all the wiping? If you use desitin, doyou use it daily or only when your LO's has a rash?
