One year old babies always hit their own heads considering the following aspects related to: 1. Otitis media. When acute otitis media occurs in babies because of discomfort in the ears, babies will relieve discomfort by hitting their heads and shaking their heads. Some babies may also scratch their ears and become irritable. In acute attacks of otitis media, there is fluid in the middle ear, which can lead to swelling of the eardrum and yellow discharge when the eardrum is perforated, and parents must pay attention if there is dry skin around the baby’s ears. This is a way of letting off steam by mutilating and hurting oneself. Parents need to care more about their babies and pay attention to their babies’ growth as well as their mental health.
