Honestly most kids who are having issues with teething would benefit from a calcium based remedy! It was a very good call on your part (especially since aconite, belladonna and pulsatilla are recognized acutes of a more chronic calc. carb (and silica, actually.) When those acute remedies are helping with comfort it's really time to look at the foundation. I had a fabulous teacher that said you can never go wrong by starting off babies on all 3 calc cell salts. I have found this to be true. They are the "earth" salt in esoteric thought and literally do create the basic foundations-the building blocks-of the body.
That's another reason I tend to just use salts for babies! They help in acutes, but where remedies can help in the midst of discomfort-and they sure do-as bluebird saw-a "teething" remedy will relieve some pain, a deeper remedy will likely ensure that this bit of teething goes smoothly and a salt will actually help shift the physiology and potentially make it where a remedy is unnecessary. Or, if it's necessary a single dose could shift the whole picture.
That's my two cents, anyway!
So you would use the 3 calc cell salts at times of need or just on a daily basis with a baby?
I tend to say use calc phos at least for a babe routinely. I don't generally see kids that don't have any indications. The others you could...and some do. I don't feel that it's overly necessary to do so.
