T.H.
It very possibly could be a milk issue, eczema is very common with that. Sometimes milk issues can present itself in strange ways, so I would talk to your pediatrician. If she hasn't been tested for citrus allergies then it could be the milk issue just looking different. I'm pretty sure they can test for things now, they don't recommend it under a year b/c it can be pretty extensive and fairly irritating. I would talk to your doctor but until then steer clear of the things you think are causing suffering!
