The changes that will occur during the sleep of the baby cannot result in the activity of the baby’s nervous system being reduced, but there will be changes in the balance of activity with the inactivity that comes from several nervous systems in the brain. Some of the nervous functions can become inactive, while other systems become active. Like the nerve cells in the cortex of the brain, it does not completely turn into inactivity during sleep. It can be concluded from this change that sleep is not necessarily a passive process, but rather an activity that can be awakened. Sleep for babies is one of the top priorities. Babies really need lots of rest, especially sleep. Its development and growth are very dependent on sleep patterns, if the baby is sleep deprived, the baby cannot grow optimally because when the baby sleeps there will be an improvement in the baby’s brain cells and production hormones can grow up to 75%. In addition, sleep also has a very big effect on health, physical, emotional, mental, and the immune system in the body.
A new baby sleep pattern will be seen when your baby is 3 months to 4 months old, the proportion of baby sleep will be more at night. In general, morning naps symptoms will stop when the baby turns 1 year old, while afternoon naps will continue until the baby turns 3 years old. The baby’s sleep pattern will gradually decrease in each period. The development of sleep in infants is directly related to the age and growth of the baby or brain maturity. That way, the sleep time needed by babies is around 16.5 hours per day for newborns. And it takes 14 hours for babies less than 1 year old, and for babies over 2 years old it takes approximately 10 hours per day.
Sleep is one of the specific activities that originates from the brain to cause sleep, this sensory input decreases in the cerebral cortex. That way stimulation in this area can produce sleep, but on the contrary if there is damage it can cause disturbance in the baby’s sleep. This wake and sleep cycle is controlled by the activity of neurons in the RAS or Retricular Activating System. This RAS consists of several systems, namely the reticular brainstem, basal forebrain, and posterior hypothalamus.
If your baby’s sleep pattern is not good, your baby will have difficulty sleeping. Babies with poor sleep quality can cause drowsiness when they play until they are hyperactive. Babies who often cry and are fussy when sleeping at night, then your baby tends to be less concentrated and not focused on doing something. Many factors usually interfere with a baby’s sleep, one of which is the condition of the baby who is hungry, wet the bed to factors that come from the environment.
