Night time is the best time for your baby to grow and develop, especially from 10:00 pm to 2:00 am, because growth hormone is most secreted at this time, so quality sleep is very important for every baby. If your baby is always half asleep at night, crying, or frequently wants to eat milk, then mothers must know the possible reasons why your baby is not sleeping well: a. Calcium deficiency If your baby is sweating a lot, easily startled, pillow baldness, poor sleep, easily awakened by slight movements at night, the first thing to rule out pathological reasons, the baby may be lack of calcium. Second, accumulation of food The baby’s spleen and stomach are not yet well developed, the feeding is unreasonable or unscientific, less activity, irregular bowel movements, constipation are related to accumulation of food, mostly occurring at night. It is manifested as a feeling of fullness in the upper abdomen, bad breath, fever, vomiting, and irritability. Third, lack of security The womb is closed, safe and warm for the fetus. After birth, babies experience different things every day, which are unfamiliar to them, and they may have more or less fear. Lack of security is also one of the main culprits of baby’s awakening. Therefore, sometimes, the baby needs to sleep next to the mother, feel her body heat and body odor, no matter how much the mother tiptoes out of the room, the alert baby will still notice and cry again. For such a baby, the mother should have enough patience, more company and give him enough security. When the baby is sleeping, the mother can caress the baby, such as touching the baby’s head or gently patting the baby’s chest enclosure, whispering and talking to him to make the baby feel settled. In addition, the mother can let the baby sleep in a relatively small space, around the crib can put some cushions, baby toys, etc.. Let the baby sleep in a fixed bed and use fixed bedding to increase the baby’s sense of security. Fourth, frightened during the day The baby is timid and easily frightened by the actions of strangers. After the baby is born, there will be many friends and relatives to visit, and they all like to tease the baby. Some times will do some frightening teasing, for example, is the first hands to cover the face and then make a ghost face to the baby, etc.. Although the starting point is to let the baby can be happy to laugh and tease, but ignore the baby’s nervous system is still relatively fragile, if the baby is frightened, the baby will sleep restlessly at night. Five, the daytime game transition Some times the mother will think, let the baby enjoy playing during the day, the night will be a good sleep, in fact, this idea is not all right. If you play too crazy during the day, or excessive games before bedtime, your baby may not sleep well at night. Because this will keep the baby’s brain nerves in a state of excitement. If the baby hears or sees a thrilling story, television images, will cause the baby sleep difficulties, dreams will appear these thrilling images, so that the baby woke up in the dream. Sixth, the sleep environment is too quiet Many mothers will think that if you want your baby to have a good sleep, you have to have a fairly quiet sleep environment. So when the baby is sleeping, the mother will close the door to the baby’s room, do things to tiptoe around, try to keep zero sound. Over time, this causes the baby to be very sensitive at bedtime, and if you leave this quiet environment, you will wake up when there is a loud noise in your sleep. This is a counter-productive effect, often the more careful, the baby is more likely to be awakened by a very subtle sound. Therefore, do not deliberately arrange for the baby to sleep in an absolutely quiet environment. VII. Excessive nipple attachment Nipple attachment is present in both breastfed and artificially fed babies. This is attributed to the mother’s habit of giving her baby night milk when she was a child, and she makes her baby often fall asleep with the nipple in her mouth. In addition to night milk, another reason is that as long as the baby wakes up crying at night, it is thought that the baby is hungry, no matter what the reason will feed the baby, as long as it can stop the baby crying on the line, over time, the nipple will give the baby a sense of security, attachment to the nipple.
