My three month old has started blowing lots of bubbles and dribbling loads, he’s also putting his fists in his mouth a lot too. Does this mean he’s teething? He doesn’t seem in any discomfort.
My little boy was the same at around this age, I thought he was teething but he didn’t get his first tooth until he was seven months old!
I think it’s just a developmental thing. Some babies do teeth early so you never know, but if he’s not in any discomfort it’s unlikely, hope this helps.
