currently I am using the mustella vitamin barrier cream on my 4-month old baby's bottom at every diaper change. I've liked it so far - baby has never had a rash. however, I'm wondering if there's a lighter / smoother alternative for day use cause I find the mustella one a little thick. so I was thinking of switching to a lighter formula for day (when her diaper is changed more often) and using mustella for night when her diaper is changed less often. any recommendations?
