Weaning is a common process when transitioning a baby from bottles to sippy cups.
Weaning from nursing or bottle feeding to sippy cups involves slowly replacing the use of the bottle with the cup. For example, a caregiver could use a sippy cup for one feeding a day and gradually increase frequency.
If a caregiver finds it difficult to wean the child, creating a new routine may help. For example, using a sippy cup as part of a bedtime ritual instead of nursing or bottle feeding may help the child associate bedtime with the sippy cup.
