The sleep of the little baby, is also a thing that parents struggle with, if parents can not recognize the signal of the baby’s sleepiness, can not be put to sleep in a timely manner, then the baby will be crying and restless, so that the whole family shall not have a good night’s rest. So parents must recognize the signals of the baby to sleep, and master the tips to put the baby to sleep. What are the signals when a baby wants to sleep? Even before babies learn to communicate verbally with mom and dad, babies can tell mom and dad through body language whether they are tired and need to sleep. Reading this body language is a key to achieving successful sleep. Common sleep-related body language includes: 1. Yawning (but if it’s one yawn, it usually doesn’t mean anything; if you see your baby yawning a third yawn or more, it’s almost time to put him or her to sleep) 2. Stiffening of movements 3. Becoming quiet and losing interest in teasing 4. Becoming irritable 5. Becoming weepy 6. Clenching of fists 7. Swinging of arms and legs If moms don’t catch babies in time, it can lead to sleeplessness. If mothers don’t catch these body languages in time, and thus don’t put them to sleep in time, then it’s likely that the babies will enter a state of overtiredness. Once in this state, then the next to sleep will be very arduous, usually half the effort. How to put the baby to sleep more effectively? 1. Wrap the baby in a light, breathable cotton cloth to increase the baby’s sense of security (they are tightly wrapped in the womb, so wrapping them will increase their sense of security). 2. Place the baby in a stroller or bassinet and rock it gently. Under the premise that there is no problem with the safety standards of strollers and cribs, this move will not hurt the child. On the contrary, it will give your baby a soothing feeling so that he or she can relax and fall asleep gradually. 3. Place your baby in a stroller or crib with wheels and push back and forth. It’s best to push back and forth on a slightly uneven surface. This is because the baby can feel a slight jiggle as it passes over the uneven surface. For example, mothers can put a piece of cardboard (half a centimeter thick) on the floor of the room to put to sleep, when the trolley passes through the cardboard box to create a protrusion, it will give the baby a slight jumping sensation, this jumping is usually soothing effect on the baby. 4, pat the little baby, start with a high frequency, after the baby slowly calm down, slowly slow down. The frequency of patting is similar to the mother’s heartbeat. 5.Provide the baby with a continuous sound. It can be a shushing sound, a soft song, soothing music, or the white noise of daily life: the sound of the vacuum cleaner, the sound of the washing machine, the rustling sound of the radio when it can’t get the band. What should I do if my baby is a restless sleeper? For babies who do not sleep soundly, it is important to consider if calcium is not being absorbed properly. Calcium absorption is related to vitamin D. Parents should pay attention to the following two points. 1. Proper sun exposure. This is the most effective, convenient and economical method. Often let the baby outdoors. In spring and fall, you can let the baby directly in the sun, and in summer under the shade of trees, so that the baby’s skin is often exposed to ultraviolet rays. Ultraviolet radiation, can promote the skin storage of 7-dehydrocholesterol, by photochemical effect into vitamin D3. sunlight exposure, can make the skin storage of vitamin D3 spare, will not make vitamin D overdose. 2, oral vitamin D. Food in addition to the liver of marine fish contain a certain amount of vitamin D, dairy (including human milk and milk), egg yolks and meat in the content are very small, grains, vegetables and fruits almost no, infants and young children every day from the natural food intake of vitamin D can not meet the needs of their development. Normal children, regardless of age, need 400 units of vitamin D supplementation per person per day, while preterm infants have an increased need, usually 800 units per day for the first 3 months, and maintain 400 units per day after 3 months, with preterm infants taking it right after birth. Normal children usually start supplementation from half a month after birth, and it can be taken until the age of 2-3 years old (up to 2 years old in southern cities and up to 3 years old in northern cities).
