Kids by age of one year will be learning new things very fast, may it be by taste, smell, words, touch and feel of their body parts etc . Most of the times, it's harmless and doesn't need any professional aid. However if there is change in the behaviour of the child such as being scared, timid, irritable or if there is any signs of infection like fever, loose stools etc along with this habit, it needs a thorough evaluation by a Pediatrician.
