Before the child is 2 years old, sleep deprivation and crying at night are common problems encountered by parents. Nursing, cuddling and many other ways to help children fall asleep 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. Generally artificially fed babies develop good sleep habits by the end of the sixth month. Good sleep habits are characterized by sleeping for about 10 hours a night. However, breastfed babies usually do not develop such habits until 8 months of age. Many data show that babies who have sleep behavioral interventions from 8 months to 3 years of age are, without exception, happier children later in life than those who do not have behavioral interventions. For babies before 6 months of age, it is important to try your best to soothe your baby every time he or she wakes up and cries in order to establish a secure attachment. There is no need to worry about “spoiling” your baby, but after 6 months, your baby will begin to cry on purpose, and once the need to cry arises, it is time to start using behavioral interventions. Baby sleep behavioral intervention methods 1, the first grasp of behavioral intervention methods is to establish a bedtime ritual. When your baby shows sleep signals, such as rubbing his eyes and starting to get restless, check his diaper as soon as possible and change it as soon as it needs to be changed. 2. Establish a bedtime and sleep schedule, such as starting a sleep ritual at 8:00 p.m. each night. A consistent nighttime bedtime helps reinforce the biological clock and makes it easier for children to fall asleep. 3. Sleep rituals should last 20-45 minutes and include 3-4 soothing activities, such as bathing, changing pajamas, storytelling, and turning out the lights; they should not include watching TV or using other electronic devices. 4. Appropriate sleep associations should be given before bedtime, and should be items within the child’s reach during the night, such as blankets or toys and other transitional items. 5. For babies who have developed the habit of being cuddled to sleep, they should be put to bed when they are drowsy but not yet asleep in order to minimize the dependence on the presence of a parent when falling asleep.
