Hello Everyone! (Again!)

On Tuesdays I had dcp come and pick up dcg who was screaming as it was out of control. I had suggested that she have her checked over by the doctor because she had an ear infection just a 2 weeks prior and I was concerned she was in pain from it (or something else) When I asked the next day if there was any diagnosis dcm said they couldn't get an appointment. So the screaming has continued and she hasn't napped at all for the last 3 days, nor has she been to the doctor. I looked in her ear today and there is a LOT of wax build up and it looks like an orange fluid has drained from her ear(s).....I'm starting to think that her ear infection has not cleared up. Seeing as I had already suggested that she get checked out by a doctor, should I still be pushing the issue with parents? I strongly think she is suffering from a persistent ear infection which is causing her screaming.Should I email the parents or talk to them in person even though I already asked that they take her? I don't want to overstep any boundaries.
