I use them all the time for cleanups after meals, etc. Never had a problem. We use the ones from Whole Foods though, which I think are similar to Pampers Sensitives.
I have but I try not to in the winter. He's been getting a rash around his mouth because he drools so much and his skin is sensitive this winter. After he eats I try to rinse his face with water over the sink instead. If it weren't for his rash I would.
I was told by a friend of mine who has two sons that you should not use baby wipes on their faces as their skin is still pretty sensitive and it can cause redness or breakouts. Hunter has mild eczema and sometimes his skin gets a little irritated but if I do use a wipe as opposed to a wet cloth, I always use the sensitive or unscented ones. It really depends on your babies skin too and his sensitivity level.
