Why does my baby always hum when he sleeps?

Generally speaking, when the baby enters a deep sleep, he will not make humming sounds. This sound will only occur when the baby is in a light sleep. Many mothers are worried about their children's physical condition. Is there something abnormal in their children's body that causes them to send out such signals? Let us now understand why babies always hum when they sleep?

Generally, children have two types of sleep: deep sleep and light sleep. When they are young, they spend relatively more time in light sleep. For example, a newborn baby has a sleep cycle of about 45 minutes, half of the time is in light sleep and the other half is in deep sleep. When in light sleep, children may smile, pout, make faces, breathe unevenly, move their arms and legs, and sometimes hum. This is a normal phenomenon. Parents should not think that their children are not sleeping well. In fact, this is just a light sleep state for children. So parents do not have to worry about whether their children are hungry, have urinated, or are feeling uncomfortable, and then take care of them or take excessive care of them. Parents should not worry that their children are not sleeping well, so it will be good to ignore them.

Because light sleep is very important for brain development. Why do I say so? Because adults usually dream when they are in light sleep, and they dream when they are in light sleep in the early morning. Children may also dream, but they will not say it. During light sleep, some of the things a person sees and hears during the day are actually stored in the brain. Sometimes brain proteins are being synthesized, and sometimes the brain is stimulated by dreams, which also helps the development of the brain. If the daytime stimulation is not enough, the brain can also receive these stimuli during dreams. Light sleep is more beneficial to children's brain development, so younger children should have longer light sleep. Especially at night, because one sleep cycle follows another, he should be allowed to sleep a little longer at night, and do not disturb him during light sleep. He can go from one sleep cycle to another, and the time gradually increases.

The above is the explanation of why babies always hum when they sleep. Sleeping is important for your baby's brain development. Most of a baby's development takes place while he or she is sleeping, and he or she makes humming sounds during light sleep. It is not a pathological manifestation. Some babies make smiling sounds. It is normal to have a smile on your face, don't disturb your baby.
