My 2.5 month old is already teething. He's constantly chewing on his hands and drooling, is always fussy, and has been running low fevers. I put my finger in his mouth and felt 2 teeny little pokey teeth. My mom said I started teething at 2 months and had 2 teeth by 4 months old. Ughhh I wasn't ready. Any suggestions? I'm about to order an amber necklace.
