Children often go through phases when they favor one caregiver over the other. This is very common and can be so difficult for parents. It can take a lot of patience and parental persistence for a child to “accept” being put to sleep by someone other than the current favored caregiver. In this situation, it can be helpful for both caregivers to take part in the sleep routine at first.
Next, the less favored caregiver can take over specific parts of the sleep routine, such as bathing, putting on pajamas, pre-bedtime massage, or reading books. Once your child is comfortable, the favored caregiver can leave the room for short periods while the other carries out their part(s).
When it’s time for the other caregiver to put the child to bed on their own, both caregivers should express confidence. Resist the urge to “rescue” your child if they’re unhappy with the change.
