On the question of whether it is better to eat hands or teethers during the micturition period, there is no unanimous conclusion, because eating hands can promote brain development, and teethers can ease the discomfort of the dental development process. Generally four-month-old babies begin to be in the micturition period, they are curious about many things, and they also like a lot of things to be sent to their mouths. As a parent, many people feel that this is bad behavior, but in fact this is part of the baby’s exploration of the world, the baby eating hands is also a physiological response. Hand eating behavior promotes eye-hand coordination and relieves unfamiliar anxiety. Either way, the main thing is that none of them can be long, and pay attention to the hygiene of the baby’s hands and teethers, so that the teethers and hands are cleaned regularly.
