Good day, daughter is one month old, she has red cheeks and it hasn't gone away for more than a week. I thought it was from the sugar and immediately stopped (adding sugar to tea). But the redness doesn't go away, it seems to be getting worse. It's scary like an burn, I'm attaching a photo, please advise what can be done.
