@kye sorry, I hardly be on here. But yeah, what @morganmommy79 said. Those are the signs that they're teething.

Thank you so much he doesn’t seem to bring doing much of those thing s right now besides fussing a lot so I guess maybe he is just getting older.

All babies are different so there are some starts teething as early as 2 or a month old while some are at 4-6. And the signs are also different except the bitings. They all start to that before the teeth really starts pushing its way out, then comes the crying and fuzziness.

I have 3 kids. One had two teeth at 2 1/2 months. One had two teeth at 3 months and one at 6 months.
Signs: drooling, chewing on fingers, swollen gums, pulling on ear or hair (it may be hurting them) some get diarrhea and my kids always got a low grade fever at some point of teething even they some say it's not associated.

@rubia__xo, what are signs that he might be teething?

All babies are different. My oldest didn't start teething until she was like 7 or 8 months. My youngest started teething around 5 1/2 or 6 months
