Most children transition successfully between 18 months and 3 years. Wait until your child shows multiple readiness signs rather than rushing due to age alone. Safety climbing behavior is often the strongest indicator it's time to transition.
Consistency is Critical: Both parents must use identical approaches, language, and consequences. Discuss strategies beforehand and support each other during challenging nights. Avoid "good cop, bad cop" dynamics that can confuse your child.
Managing Multiple Children: If transitioning due to new baby, begin process 2-3 months before birth. Avoid making transition about "giving crib to baby" - frame as growing up achievement. Consider separate bedrooms during transition to prevent sleep disruption for other children.
Temporary Disruption Planning: Expect 2-4 weeks of potential sleep disruption. Plan important activities for later in transition period. Consider taking turns with night duties if both parents work. Communicate with caregivers about new bedtime routines and expectations.
