Breastfeeding my youngest who is nearly 5 months, his nappies have been greenish for a good few weeks but are now forest green and quite mucousy. He also has some patches of rash over his body which are quite subtle and I thought were dribble/sweat rash as round the neck and creases but they’re looking increasingly eczema like. I’m going to make an appointment with the HV but all Googling points to CMPA, do you think this is what it could be? Thank you
