Why do babies put everything in their mouths?
Babies typically start mouthing by 4 months, once they’re able to bring their hands to their mouths and suck on their fingers.
Once babies discover that their hands and fingers are always on hand, they'll realize that they have a built-in way to soothe themselves. Babies start to realize that their hands are useful tools for exploring new environments & objects by putting things in their mouths!
Before a tooth erupts, you may notice an increase in your baby's desire to stick everything in his or her mouth. Rubbing the gums helps to ease the pain & can actually help a tooth to come through.

Babies are wired to mouth objects, so let them - safely of course! Keeping your baby busy with, or interested in things that they can safely mouth is key.
