I was just wondering if anyone knew why a 4 1/2 month kid, who isn’t even teething yet, can start gnawing on everything? At first, we assumed it might be teething, however weeks have passed with no evidence of teeth 
Is it merely an outgrowth of their oral explorations?
mentioning that teething could take a while. My son’s first tooth came out after two months of teething symptoms.
@Whitney Thank you, that’s wonderful to know!
When my kid was four months old, she seemed irritable, was always drooling, and I assumed she was teething. Now that she is six months old, she still doesn’t have any teeth! Right now, I dunno.
