Teething Baby

In October 2012 I took my baby, then eight months, to a homeopath. This was a proactive decision to support her overall health and immune system, as we have decided not to vaccinate her at this time. One symptom that had appeared about a month earlier was dry patches on my daughters chest- the pharmacist said it was ringworm and we treated with topical cream, but it was actually a bit of eczema. After the intial consultation the homeopath, who is now out on maternity leave until March 2014, gave one dose of Sulphur 200c to treat her constitutionally and said to wait two weeks and see if there was any change. She also sent us home with chamomilla drops for teething. After a week the dry patches on my daughter's chest and back cleared up and the teething drops seemed to be working well. At the follow up consultation one month later everything was working well. Shortly thereafter, it seemed as though the teething drops were no longer effective and we were advised to tap the bottle firmly on the bottom five times and give her a dose every morning and night. It still doesn't seem to help that much because she pulls at her ears and grinds her teeth, and doesn't sleep very well at night (though that may be another issue altogether). Also, the dry patches on her skin returned and are more numerous. She also has incredibly red and very dry cheeks, some teething rash around her mouth and some diaper rash. I give her a 200c tablet of Sulphur each morning and night to try to help with this because the homeopath said it worked very well on diaper rash- it does seem to help with the diaper rash on her bum but is maybe making the dry patches and her cheeks worse. I described these symptoms to the homeopath but was advised to continue with sulphur. I have since read that once sulphur stops working it can create negative effects. As I mentioned, the homeopath is now on maternity leave and I am anxious to know if at this point the sulphur is doing more harm than good. Also, I read about belladonna as a remedy for teething and thought it might be worth trying. Any suggestions would be appreciated. Thanks!
