I've found these two products to be crucial to helping manage Hollis' teething pain.
I used Camilia when he was an infant, and "graduated" to the Hylands teething tablets when he was eating solid foods (even though the bottle says it's fine to give to an infant).
I've only been able to find the Camilia at Wholefoods. The Hylands tablets are almost everywhere.
The thing I like most about Camilia is that you can buy a box of 20 doses and stash 5 all over the place (your purse, pocket, at grandma's, in the car, etc.).
Hollis loved the Camilia liquid doses and would instantly start to feel better whenever he saw me grab one. He eventually felt the same way about the tablets.
