If your toddler has climbed out of the crib, treat it as a safety issue first. A calm bedtime response can help later, but it does not make a crib safe once your child can escape it.
Stop and check the crib’s limits
Follow the manufacturer’s instructions. CPSC guidance says to stop crib use when a child begins to climb out or reaches 35 inches in height. A product may have additional limits.
Avoid climbing-prevention modifications
Do not add a tent, restraint, extra mattress, or improvised barrier. Do not rely on rotating the crib or using restrictive clothing to keep a capable climber inside. Lowering a mattress cannot override a limit that has already been reached.
Prepare a suitable next sleep space
Use a bed appropriate to your child and the product instructions. Childproof the room: anchor furniture, secure windows, and remove accessible cords and choking hazards. Check how your child can reach you and how you can reach them.
Keep reassurance and routines familiar
Explain the change simply, practice the routine in daylight, and respond calmly to nighttime needs. The new freedom may take some adjustment. Ask your pediatrician if you are unsure how to make an early transition safely.
