My LG is almost 4 months old and has had this rash for a week, it has only got this bad in the last 2 days. She has no fever and is completely herself. Could it be a teething rash? Maybe an allergy to fabric softener? She is breastfed and I don’t eat dairy due to her reacting when she was younger (didn’t react with a rash). It’s not this red unless it’s been in water, but you can feel it at all times.
