My daughter has this bubbly/tiny blister looking rash on her tailbone. She is 8 months old today and she has never had this before or a diaper rash before. She had a yeast diaper rash infection when she was 2-3 weeks old due to me being on antibiotics and I nurse her. I haven’t eaten any new foods lately and the only two new things she had today were Gerber apple juice and Gerber Strawberry Apple Puffs. But she has had applesauce and something with strawberries in them before and has never had a reaction. She is on antibiotics for an ear infection so it could be a yeast infection again and I’ll keep an eye on it and if it doesn’t go away I’ll bring her in, but has anyone seen anything like this before or have any idea what it could be or could be from?
