The APP is mainly used to calculate the changes in babies' sleeping time, feeding time, height and weight.

According to the characteristics of different baby feeding methods are different, the correct feeding methods of babies are divided into the following points:

1. Different feeding intervals. According to the rest time of each baby, play time, crying time and so on to distinguish, the feeding interval of each baby is different, some babies to feed 180 minutes apart, some babies to feed 240 minutes apart, according to the different circumstances of this interval time, can provide a specific feeding interval standard, for every 3 hours for feeding once, Ensure the baby's normal physiological needs, but also appropriate for the baby's needs.

1. Infant sleep and growth

Just like recharging a battery, a baby can recharge and recover the energy expended during sleep. When the body is asleep, the secretion of growth hormone, which is closely related to growth and development, reaches the maximum. Infants can produce three times as much or more growth hormone when they are asleep than when they are not. Sleeping can provide sufficient growth hormone for the body, promote the development of the child's nervous system and brain mature, children can also grow up healthy. Hormones that stimulate muscle growth and help it recover function are produced more when children sleep. These growth hormones help children convert body fat into energy in muscles and make their bodies stronger. Therefore, sleep is very important for children's growth and development and healthy growth.

2. Infant sleep affects cognition

For half of a baby's sleep, the brain is organizing, reassembling, and recognizing the information it has received during the day. Some parents may think that a child's eye movement is a sign that he is waking up. Parents should pay attention to the quality of their children's sleep, do not wake up their children casually, to help children develop good sleeping habits. Studies have shown that children who don't get enough sleep are less able to concentrate. If sleep is not enough for a long time, the child will not be interested in the outside world, will affect the child's mood, and can not adapt well before school.
