Thanks for the replies everyone.

Karika - My main fear is just not really knowing enough I guess. We have been really lucky over the last 11 months and have had to give absolutely no medicine except for 2 doses of Tylenol (one at 6 months and one at 9). So she has never had a fever, ear infection, cough...she had has a few runny noses, but that is the extent of it. I am not really scared of OTC medicine, just a little weary and uneducated on the subject. I also just prefer natural if I can get it, BUT...
I have had a few experiences where the natural stuff hasn't cut it. For instance, DD got a little diaper rash last weekend and I decided to use the California Babies cream with Calendula, the rash got worse and the cream seemed to really hurt her. After 2 days I broke down and used some Desitin I had gotten at my shower and the rash was gone by the next morning. So I do see the benefits of being prepared with both.
I love Hylands, so I will see what they offer in the realm of allergy attacks and I will also check out the Oxy Hives, thank you for the recommendations

.
I think I will pick some Benedryl up just in case. DD hasn't had any allergy issues up until now, but a camping trip isn't where I'd like to find out that she does. Also, there is Poison Oak (Ivy?) there so I may as well prepare for the worst.
Thanks again for the replies!
