It also makes me feel lonely and cry because my mom and dad aren't nearby and I don't have the toys I use all the time.After 7-9 monthsWhen it becomes possible to distinguish the faces of people such as moms and dads, the cases of crying due to shyness and the disappearance of the appearance of moms and dads often lead to crying.

It is said that about 1 in 5 babies will see this HSC, and they may start crying with a slight stimulus such as hugging or feeding the baby. It is important to reduce such external stimuli as it reacts sensitively to changes in room temperature, loud noises, and bright light.How to Deal with a Baby's Crying Suddenly What if your baby cries or suddenly cries hard?

Breastfeed and change diapers to see what your baby is doing.Check your physical conditionMake sure your clothes aren't tight and that you don't have diaper rash.

It is also recommended to make the vinyl crumple so that you can hear the sound of "see" so that you can remember when you were in your stomach. Also, when you go for a drive, you may stop crying with a pleasant vibration.What you can't do for a baby who can't stop cryingIf the baby keeps crying, the adults around him will feel stressed.

But that's only for a very short time in a safe place like home. Do not leave your baby for a long time, not only at home but also on the go. Such behavior may also be considered abandonment of childcare.Shake violentlyFrustrated moms and dads tend to shake their babies violently. However, the baby's brain is still very soft, and if it is shaken violently, the blood vessels and nerves in the brain may break and cause damage. This is called "infant shaking syndrome," but it can lead to speech problems, difficulty walking, blindness, and, in the worst case, death.Newborn babies may cry for a reason, as well as for no reason. If the baby starts crying, try various things such as healing and taking care of them, and check the baby's physical condition.

Crying for no reason can be a pain for any mom or dad, but it will eventually settle down as they grow up. I want to keep up with the crying, thinking that the baby is growing up so well that he can cry loudly.
