Babies banging their heads with their hands may be caused by physiological factors, eczema or mosquito bites, otitis media and other reasons. 1. Physiological factors: the baby may be imitating or playing with his hands. Babies have a strong ability to imitate, and if this action has appeared in cartoons or adults, the baby will follow. 2. Eczema or mosquito bites: It is important to observe whether the baby’s head has eczema or scalp discomfort caused by mosquito bites, which leads to the baby’s head flapping. 3. Otitis media: If your child suffers from otitis media, he or she may feel discomfort and tinnitus that your child cannot describe and can only be relieved by patting the ears. When babies appear to tap their heads with their hands, they should go to the hospital for examination in time and be treated under the guidance of the doctor. Do not delay as it may be dangerous.
