Babies cry at night when teething, which usually lasts for about a week, but there is some individual variation and it needs to be determined on a case-by-case basis. Every infant exhibits different symptoms during teething; some may have no symptoms, while others may drool, refuse to eat, and cry at night. If night crying occurs during teething, it may usually last for about a week. During this period, parents may give their infants more soothing and companionship. As the baby gets used to the situation, the crying will gradually stop and there is no need to worry too much. After teething, it is also important to take good care of oral hygiene and cleaning to avoid premature inflammation and caries. During the teething process, you can use teething sticks to promote tooth eruption, and you can also eat foods such as mashed potatoes to help exercise chewing.
