I assume this is your first baby? You may find that as your baby gets a little older, you constantly have to pick up everything within reach for fear that baby will put it directly in their mouth. You also take great care in making sure that all of their toys are cleaned on a regular basis because no matter what kind of object it is, baby always finds a way to get it in their mouth.
So why do babies put everything in their mouth? Babies have no way of really feeling an object in their hands because they have motor skills that have not been fined, tuned or developed properly. Babies’ mouth is full of nerve endings and babies typically have complete control of their mouth and tongue. When babies pick an object up, no matter what it may be, they will typically go straight to their mouth with it so that they can feel and try to understand whatever it is they are holding in their hands. As babies grow older and gain better use of their hands, less things go in their mouth because they are able to grasp on to an object and study it better.
