Help! What started off as baby acne is now a rash.

tashadee75

My LO started getting baby acne around 5 weeks. The pedi told us to leave it alone as it would go away. He is now 3 months(14 weeks) and what was baby acne on his cheeks and chin is now a rash that will not go away. It doesn't appear to itch or irritate LO, but it has its good days and its bad. Sometimes it seems raised... sometimes it seems smoother. 

We've been using Aquaphor and can't really say it's been helping.

Anybody have any similar issues or experiences? Any help is appreciated.
