Sleep deprivation and nighttime crying are common problems for parents until their child is 2 years old. Many ways to help children fall asleep, such as nursing and cuddling, often result in babies resisting falling asleep, taking a long time to fall asleep or waking up at night. In the face of these situations, the main treatment is behavioral intervention. In general, artificially fed babies develop good sleep habits by the end of the sixth month. Good sleep habits are characterized by a sleep that lasts about 10 hours. Breastfed babies usually do not develop such habits until they are 8 months old. Many sources show that babies who have sleep behavior interventions from 8 months to 3 years of age invariably become happier children later in life than those who do not have behavioral interventions. For babies before 6 months of age, it is important to do your best to soothe your baby each time he or she wakes up and cries in order to build secure attachments. There is no need to worry about “spoiling” your baby, but after 6 months, purposeful crying starts to occur and once the needy crying occurs, we need to start using behavioral interventions. If, in the process of developing sleep rituals, the child falls asleep with violent cries for help from the parents or wakes up at night, the method of systematic neglect (or cry immunization) is needed. This method requires the sudden or gradual withdrawal of parental help when the child falls asleep or during the night. Consistent use of systematic neglect is the only way to get the child to fall asleep without parental help. Usually the sudden withdrawal method is difficult for parents to accept, so here is the main introduction of the gradual cry immunization method. 1. During the sleep ritual, if there is a drowsy performance, put the baby in the crib immediately and leave, you can close the door, watch the clock and give the baby 5 minutes, when he may fall asleep. 2. If after 5 minutes he is still crying, you should go into the room, sit the baby up, give him the toy, do not hold the baby, or give reassurance, but this reassurance should remain short (1-2 minutes) and neutral, (e.g. patting the shoulder, not picking up and hugging). Wait for the sign of sleepiness to appear again. 3. Put the baby in the crib again and leave. You can close the door, look at the watch and stretch the time interval to check the child, such as 10 minutes, 30 minutes, etc., depending on the parent’s tolerance to crying and the baby’s temperament to decide the time interval. If still crying, repeat step 2. Within 4-10 days, the length of time needed depends on how deep the baby is in the habit of using deliberate crying. The treatment is more difficult when the baby and the parents have developed the habit of sleeping in the same bed. It is necessary to use a special plan: 1. such as 3 days to establish a bedtime ritual and a target bedtime; 2. when the sleep ritual is initially established, start 3 days to quit the habit of cuddling and milk sleep. When the child is drowsy, put the child to bed and pat him/her to sleep. If the cry is obvious are using the above-mentioned cry immunity method; 3, after weaning from holding sleep, 3 nights parents simply accompany the child bedside, without giving any soothing, exercise the child’s ability to fall asleep on their own; 4, then 3 nights in the bedroom door; 5, and finally in the method of leaving the room. So it is generally not recommended to sleep in the same bed, of course, parents can choose to do so, but, for this practice leads to complex consequences, often who can not help! Points to note: 1, if the baby is sick, do not use this method, during the illness to give the baby maximum effort to soothe the baby to recover as soon as possible. This sleep training can be done later; 2. The child’s delay in going to bed should be ignored; 3. Behavioral interventions should be consistently implemented to avoid intermittent reinforcement of undesired behavior. At the beginning of treatment, the child’s protesting behavior is likely to escalate temporarily, which is called “cry-free rebound”, and if it does not persist, the cry-free rebound behavior is reinforced. In short, babies who receive this behavior training will become happier once they develop the habit of falling asleep on their own. Therefore, before starting this training, it is important to agree with family members, combine the child’s temperament and parental tolerance, make a plan and stick to it, and you will definitely achieve good results.
