there is this powder that i swear by.
i tried everything with my two when they were teething, all the gels, calpol, teething rings, nothing worked, then i tried the powders, GOD SEND!!! they work almost instantly.
i think they are called Ashton and parson teething powders.
they are little wraps of white powder that you put on to the babys tongue, you can buy them in any chemist.
Im going to stock up on them for when this little one arrives
