It usually takes 3 to 7 days for a baby to wean and cry. However, the different character of each baby, the different dependence on breastmilk, the way of weaning, etc., may have an impact on the duration of the baby’s crying. It is best to wean gradually. Reducing the amount of breastmilk before weaning, so that the baby can reduce the dependence on breastmilk, can to a certain extent reduce the time of baby’s crying during weaning. In addition, during the weaning period, try to let the baby have contact with other people in the family, so as to distract the baby’s attention, which can also reduce the time of crying. If the baby is less dependent on breastmilk and has better contact with other people, the crying time is shorter and may take about 3 days or even less. If the baby is more dependent on breastmilk and does not have good contact with other people, the crying time will be longer and may take 7 days or even longer. Therefore, the duration of baby’s weaning and crying varies from person to person, and there is no specific number of days specified.
