We have successfully tried an old Baltic tradition- my son is wearing an amber teething necklace and we notice it certainly takes the edge off of his discomfort. Amber is made of pine resin, which has anti-inflammatory oils which dissolve into the skin due to body heat. The necklaces sell for $15 and up and are knotted around each individual bead to prevent accidents.
Hyland's teething tablets contain a combination of homeopathic remedies designed to cover the gamut of symptoms. You may be able to get an even better result from homeopathy by figuring out which "picture" of symptoms your daughter has. My husband studied classical homeoapthy, and we have been able to determine with both of our children which single remedy (rather than several lumped together) is best suited for each. Here's a simplistic tutorial for the common "ABC" baby remedies:
Aconite- an aconite baby is likely to have a wide-eyed (perhaps with pupils dilated), even anxious or surprised look and tends to toss and turn in sleep with shrieks and often bites fists.
Belladonna- a belladonna baby usually has cheeks RED, swollen, and HOT. They tend to seem angry (although may be normally quite good natured when not teething).
Chamomilla- a chamomile baby is just completely irritable & often has bouts of diarrhea when teething, as well as a red spot on one cheek (and sometimes the other cheek may be quite cold and pale). A chamomilla baby often does not like to chew on anything because pressure aggravates their sore gums. This type of baby often demands to be held and cries if held still or set down; is hard to comfort.
It sounds like you are very compassionate and a gentle mother. I rememember being very afraid too when my son would have fevers and diahrrea while teething, and becoming emotionally worn out from constantly comforting him. What helped me most was an article I read about holistic attitudes towards children's immune responses. It spoke of "honoring the illness"- that the goal of home remedies is not to stop the symptoms, just to reduce the severity. Honor what the body is trying to do and facilitate the conclusion of the process without complications. For vomiting, try to avoid food or liquids for 2 hours. The stomach wants to rest and continuing to add things can prolong the vomiting. Sucking on ice chips or, at your daughter's age, maybe a wet washcloth, until the stomach has had time to rest, then introducing hydarting fluids- coconut water is ideal- and if your child is dangerously dehydrated, you can administer 50% fruit juice diluted with water rectally with a bulb syringe (hopefully it doesn't come to that- this is more for extreme cases like salmonella). But, I found this to be very affirming in that when a child vomits they tend to resist food and water- and so does our dog- for a little while- guess maybe their bodies know what they are doing! For diahrrea, nothing works better than broth- preferably a homemade chicken broth given a few tablespoons at a time. The gelatin in a broth made with not just meat, but bones, binds up liquid in the colon and gives it bulk to stop the loss of fluids. After we roast a chicken I put the carcass in a stockpot with water to cover, carrot, onions, and celery and after bringing it to a boil I let it simmer up to 3 days. Then I strain it and store it in the freezer for such a "healing crisis" as this.
When your child has a fever, holding her is often the most soothing thing you can do. As long as the fever doesn't go over 103 you probably are better off letting it take its course because we generate this type of heat on purpose in response to what our immune system understands we need to facilitate things. Our bodies are very wise, and the holistic attitude to "supressing" symptoms (such as taking pills to make fever diminish) is that rather than a surface acute condition which the body will have a struggle with, then overcome and be stonger for it- supressing the body's struggle will lead to a more chronic, internal problem. Just like with emotions- dealing with difficult situations to resolve them, even if it requires confrontations or turmoil we would rather avoid- facilitates healing rather than stewing over things inside and generating low level long lasting stress which takes a toll and then eventually begins to resurface in worse ways than it started. A child's ability to generate a good fever is a positive sign, because it is exactly this heat pattern which stops pathogens from replicating quickly if an infection is beginning. The more often we supress fever, the less the body will try to generate this heat.
My 14 month old just came down with a sudden fever this evening, and I made sure he was comfortable in cotton clothing so his skin can breathe well and wrapped him up on my chest in a baby carrier and just walked and walked with him in the dusky, calm evening. He just went limp in my arms and completely relaxed, his breathing became steady with mine, and he is now sleeping peacefully in his crib. I think when they sense that we believe in what their body can do to heal itself and we are not worried, they just receive our empathy and progress in their recovery. So cuddle with your baby and sing her a song, and believe in her! You're a great mom.
