My DuBear, Jaidyn, started teething pretty early. His bottom two middle teeth popped out at 3months. He is now 9mo and has 8, 4 on top 4 on bottom, and is working on the K9s on the bottom. He puts everything in his mouth and when they were coming in he let us know it. He eats what we eat, some of the toddler grad foods, and stage 3 and is chewing just fine. I think everything is fine.
