Sleep is essential to human activities especially for children. Consider the needs of the child to sleep, because during sleep, infant brain growth reaches its peak. Not only that, muscle, skin, heart and vascular system, metabolism, and bone growth in his sleep. That's because children's body produces growth hormone three times more than when she awoke.
Referring to one study Sekartini et al in 2004-2005 in five major cities in Indonesia (Jakarta, Bandung, Medan, Palembang and Batam), Rini reveal, as much as 72.2 percent of parents think sleep problems in infants is not a problem or just a minor problem.
The same study also revealed that there were about 44 percent of infants who experience sleep disorders such as frequent waking at night and sleep deprivation. "The baby is said to experience sleep disturbance at night when less than 9 hours sleep, woke up more than 3 times and duration of awakening more than 1 hour. During the visible always fussy baby sleep, cry and difficult to fall asleep again," said Rini.
