My lo has had little faint red bumps on her back only - sometimes there is red around it. I have been putting baby lotion on it but curious of this should be a concern. It’s only her back which is so weird- the bumps stay, sometimes the redness appears. Weather allergies? Food allergy? (Wouldnt it be all over her body) just sensitive skin ( please dont say covid because its not that). I have an appt wed for her 6 month check up. Hard to tell in pic
