I don't know what I would do without Homeopathy. I started learning when I was pregnant the first time, since homeopathics can be used even during pregnancy, since they are highly diluted and only help the body heal itself ( don't confuse Homeopathics with other natural remedies and herbs).
I have 7 books now and a collection of single substance homeopathics that help if used correctly ( you have to find the right substance for your condition).
If not experienced or in case of a complicated disease, see a pro.
Otherwise you can start by taking Aconitum (potency C12 or 30) when you feel like you are getting sick ( or your kids) at the first symptoms and see for yourself.
My twins had chronic ear infections and I was told to by my ENT to have surgery (tubes) or long term antibiotic treatment. I didn't want either, asked for 6 weeks of time and saw a homeopathic practitioner.
When I returned to my ENT, he said "I don't know what you did ( and he didn't want to know), but their ears are A-o.k. Since then we didn't have a single ear infection.
