Oh my god, the baby will laugh.
OMG, will turn over.
The 4-month-old baby is no longer as confused as before.
However, many people found that 3 months ago, they slept very well, and the baby suddenly began to wake up frequently at night, and it was difficult to sleep.
What's going on?
Characteristics of 4-6 months of sleep
Melatonin secretion: the baby began to secrete melatonin from 3 months, the biological clock began to master the circadian rhythm, if you do not sleep at the point will be excessive fatigue, no longer like the previous night to fall asleep if the gap is larger will not affect too much.
Transition of sleep patterns: Begin to switch to adult sleep patterns, quickly enter deep sleep after falling asleep, and then turn shallow, and by 5-8 months, it is roughly the same as that of adults.
Disappearance of physiological reflexes: Most of the physiological reflexes have disappeared, and the baby has begun to have the ability to control his body.
The development of big movements: The baby begins to roll over and begins to be able to grasp things.
Cognitive development: The progress of vision and hearing, seeing farther, responding more quickly to sounds, and beginning to interact with people. Adapt to the outside environment and slowly begin to understand how the world works.
Resisting Sleep: What's Wrong with These Two Points? The baby is beginning to have control over his body and can see a little more clearly. Wow, this world is really new, I just want to see more, play more. Anything is new to the baby, the baby resists sleeping, wants to play, and cries as soon as he enters the room knowing that he wants to sleep.
Golden time for sleep training: After a few months of running-in, parents and babies have adapted to each other. Regular wake-up-sleep patterns also begin to form around 4 months. The biological clock begins to master sleep, which is the best time to establish a regular routine.
And this month of age babies begin to recognize the rules, is the best time to start to establish and change. For example, the baby has been sleeping in the hug, it will begin to form a cognition, think that when falling asleep is such a pattern, so at the end of each sleep cycle into light sleep, it is found that it is not hugged, it will wake up to find the parents to hug, this is not insecure, but has been holding and coaxing the baby to understand that sleeping is holding sleep.
6 months ago, in fact, the baby did not separate anxiety, will not obviously recognize people, exclude strangers, wake up when anyone can hold, and why will it be found that when it comes to sleep, only someone can hold, because the baby has formed the idea of who sleeps or the mother's milk, so when he is sleepy, he will look for a specific person to perform sleep.
Note: Many experts recommend not to sleep training for babies under 6 months, IPHI does not advocate sleep training for babies under 4 months, most of them refer to cry immunity or cry control and other ways that the amount of crying may be more, and does not include regular work and rest and gentle step-by-step sleep behavior training.
Difficult to coax sleep: the soothing strength rises sharply and chaotically, from sleeping with sleeping milk to not sleeping with milk, this is also combined with the above points plus anxious to coax children to sleep, resulting in more and more use of the method of coaxing, the child is more and more chaotic, and finally it is very difficult to coax sleep.
Correspondence
Regular schedule: To start establishing a regular schedule, it is best to fix the time of falling asleep at night at the same time. Especially day and night upside down, can not sleep during the day, do not sleep at night, stay up late situation should not appear again.
Turn over: Some babies turn over on their heads high, and then wake up, this may be too many people saying 0-3 months to let the baby practice looking up, resulting in the baby to turn over on the chest to look up, causing this reflex action, the baby turned over naturally up.
This is more than enough for the baby to practice lying down during the day, and you can also let the baby sleep on his stomach under the whole process of nursing, and get used to it.
(There is nothing wrong with sleeping on your back is the safest position, but when the baby learns to turn over, he will choose the position he feels comfortable to sleep, trying to change his sleeping position is not practical, fixed sleeping position is even more undesirable, the fixation will have the risk of getting stuck in the baby, avoiding any items on the bed will be safer, after the baby will turn over, it is best to remove all the items in the bed.) ）
Sleep ritual: a good time to establish a sleep ritual, go back to the room, wear a sleeping bag, turn off the lights, pull the curtains, etc., so that the baby can know that it is time to sleep.
(Let's not talk about sleep training, change to sleep with sleeping milk, this is too long, first say that it is difficult to sleep, how to resist sleeping.) ）
Unified sleep method: Coupled with the above sleep ritual, only one sleep method is used to quickly help the baby understand the requirements and rules of sleep.
Fixed sleeping place, can only be coaxed to sleep in the room, do not stay in the room when awake, even if the baby is crying, it is necessary to soothe in the room.
In this way, the baby will soon know that going back to the room, wearing a sleeping bag, holding the pat is to sleep, this time is not to go out to play. Generally, the baby will understand this pattern very quickly, and if you go back to the room at the right sleep time to go to sleep, there will be no more problems of sleeping for half an hour and crying
work and rest
As the amount of milk drunk increases, the feeding interval can be extended to 3.5-4 hours.
During this period, it often appears that the mother is still feeding according to 2.5-3 hours, the baby is not very hungry, just drink a little, and then the mother feels that the baby does not drink a lot, after 1-2 hours and replenishes the milk, and then falls into an infinite cycle of the baby is not hungry and the mother has been feeding the process, that is, many people think that the anorexia period.
3 small sleeps during the day: With the elongation of the feeding interval and the awake interval, the daytime will be converted to 3 small sleeps in 3-4 months, the easy round of 4 hours, and the two long and one short sleeps will become 5-6 months.
If you still have 4 small sleeps in 4 months, you should pay attention to your work and rest.
Work and rest reference is shown in the figure:
Total sleep: The ideal amount of sleep is 14.5-15 hours, a little less than 13 hours.
Interval between awakenings: 2-2.5 hours, do not exceed 3 hours.
Nighttime sleep time: Reference is 8 o'clock, the error before and after the selection of night time should not exceed half an hour, because the biological clock has been formed, and the confusion of the night sleep time is easy to cause frequent night wake-up and early wake-up problems.
Joe's dad's broken thoughts
Sleep rituals, work and rest, wake intervals, sleep training these details can go to the previous article.
4-6 months is the sleep regression period, but also the golden time for sleep training.
The so-called crisis is a turnaround, if the baby's sleep status of 0-3 months is not good, at this time can disrupt the work and rest to re-establish, and at this time it is easier to adjust the baby's sleep behavior.
