teething tips?

Chelsey
Crazy as it may seem, my almost 3 month old has begun teething. We noticed 2 little teeth on her lower gum line Monday and since then have noticed she is more fussy, drooling, gnawing on her fists (regardless of her eating schedule). So far we have tried Tylenol and I hold a teether for her. Any other ideas/tips/tricks to make it less icky??
