My DD is 5 weeks + 3 days. We’ve had quite hot weather the past couple of days and I’m wondering if this may be heat rash? It’s not bothering her. I’ve taken her clothes off to allow air to get to it but I’m worried it’s something serious? She’s had it the past couple of days and it only really seems to be on her neck and chest. Maybe a little on her back but it’s not on her legs or arms at all.
What do you think?
