My son climbed out of his cot at 18 months. I found him standing in the hallway at 6am looking extremely pleased with himself. We moved him to a floor bed that day. Then he started climbing the bookshelves. Then the kitchen counters. At some point I accepted that I had a climber and my job was to make the environment as safe as possible rather than to eliminate climbing entirely. Climbing is actually brilliant for toddler development. It builds gross motor skills, upper body strength, problem-solving, spatial awareness, and risk assessment. Trying to stop a climbing toddler is both futile and counterproductive. The goal is managed risk, not zero risk. Anchor all tall furniture to the wall without exception. Bookshelves, wardrobes, chest of drawers, and television units must all be secured. This is non-negotiable. Toddlers can pull over unsecured furniture and the consequences can be serious. Remove items that create a climbing invitation: chairs pushed up to benches, stools near counters, toys stacked near windows. Create legitimate climbing opportunities: a toddler climbing frame, a soft play mat with low cushions to climb over, a children is slide. Channeling the climbing instinct into safe outlets reduces dangerous climbing significantly. Outdoor climbing on age-appropriate equipment is excellent: it provides the proprioceptive and vestibular input toddlers are seeking through climbing and does it safely. Teach safe climbing rather than just saying no: teach your toddler to climb down backwards from heights, to test surfaces before putting weight on them, and to call for help when stuck. These skills serve them much better than a blanket prohibition they will ignore anyway.
