My nearly 5 month old has just developed this rash on her chest but also on some areas of her neck. It looks quite dry in places also. She is EBF but we have just introduced a bottle and I’m not sure if this is related where she’s getting a lot more of the milk down her (even though we are using bibs) and it’s damp/warm. Opinions greatly appreciated and any advice on what best to clear it up. Luckily it’s not bothering her at all and she’s not itching it.
