The child sleeps less is related to various factors, more common are the lack of trace elements calcium and neurological dysfunction, and the usual diet also has a great connection. If the baby is usually deficient in calcium, it will lead to easy fright and crying, which will also lead to low sleep, and should be treated with timely calcium supplementation. If the low sleep is caused by nerve dysfunction, you can take vitamin B1 and vitamin B12 orally, which are very helpful for regulating the nerves. If the baby often drinks milk tea or drinks rich in caffeine, it is also likely to cause too little sleep. If breastfeeding, the mother often drink tea and coffee, through the milk for the baby to absorb later is also likely to lead to too little sleep, or even excitability, so the mother should also pay attention to improve their eating habits.
