His hiney is so red! I think it's the combination of the heat and all the formula that he drinks. Poor baby was screaming when I tried to wipe him. We've tried Burts Bees and not only does it smell horrible, he screams when I put it on him. His teachers said that Butt Paste was pretty strong too. So we are sticking with vaseline/aquaphor. He's fine otherwise; it's the wiping, even when we do it gently, that stings:-(
