Oh, dear. It's a bit early; but not unusual for teething to start at that age. Forget frozen bagels or other food items that may choke a child. I used a clean wash cloth and placed it damp in the freezer. The cold will alleviate the pain of teething and the cloth will not cause a choking hazard. Let the baby do this in the high chair or rocker, as the cold also affects the hands he is using to gnaw on the washcloth. A bib or cloth diaper over the neck and chest works to soak up the drool...
Take care, dear, it's always a phase we go through...
