I can only tell you our experience. My son had 8 teeth by eight months age. He began teething at 3 months and had two teeth a month later. He drooled so much that he sometimes wore a bib to keep his shirt dry. It is difficult to look in the mouth so with a clean finger you can feel in there to see if a tooth has erupted. Prior to eruption I noted the swollen bumps, meaning a tooth was coming in. My son wasn't interested in chilled wash clothes but I hear some babies are. I did try freezing breast milk and placing in a mesh feeder, which I held for him, but he wasn't very interested in that either. I was hesitant to use some foreign made teethers though but did find a teether that I could chill and he seemed to like. It's made in Germany, but sold in Babies R Us here in the US.
Overall he seemed soothed by babywearing (which likely kept his mind off of his teeth too) and being with me 24/7. We co-sleep and he would nurse but he never stayed up due to pain thankfully, some babies do. That may not be enough comfort though for some babies but they may experience pain differently. Overall though he got through it quite easily for which I am thankful, we shall see how the rest of the teeth come in. I never medicated him nor used any homeopathic remedies.
