Ok now there are homeopathic alternatives but basically these have not been proven to work. What is best is that you take your child to a professional Classical homeopath to find their constitutional remedy. When this is given the body will be in a better position to fight any diseases it comes across. Other than that if your child does get a disease the child can be treated with homeopathy which will assure that the disease is over with quickly without too much distress.
I admire your stance re vaccinations. I have just one family where the kids have not been vaccinated and they are basically very healthy. The 4 yr old has glue ear and the doctors want to put grommets in which Mumdoes not want. He has improved his hearing with the second remedy I gave him. His ears went pop!! The trick is to find the constitutional remedy for the child in many cases of a chronic problem so find a classical homeopath through recommendation and sign your child up.

Are you aware of the fact that if you let a child have a common childhood disease that after it they grow very quickly, physically and mentally. The body also learns how to fight disease and the thymus gland gets to do what it should be doing, resisting disease which it often doesn't get an oppotunity to do in vaccinated kids!!
