Convertible Crib
When you purchased your baby's crib, you may have opted for a convertible crib that you can take apart and convert into a toddler bed. To make the conversion, you usually remove one side panel and lower the mattress to its lowest possible position; check with the instructions that came with your specific crib. Some crib makers print the instructions on the bottom of the crib itself, making it far easier to transition.
Traditional Toddler Bed
You can buy a separate toddler bed. They come in a wide variety of materials, from hard plastic to metal to wood. Buy a bed that matches your child's bedroom, or take her along and let her pick out a bed and/or bedding fashioned after a favorite character.
Weight Limit
According to Consumer Reports, most manufacturers of convertible cribs and toddler beds have a weight limit of around 50 pounds. To find the recommended maximum weight of your bed, refer to the instruction manual, check the manufacturer's website or call the company directly. If you are not sure of the make or model of your crib, there is often an identifying mark on the bed with a brand name. Start your search there.
Average Weight of Toddlers
Most toddlers weigh less than 30 pounds by age 2, although there are individual differences based on genetics and diet. By age 3, toddlers weigh an average of 30 to 33 pounds, and by age 4 they weigh an average weight of 35 to 37 pounds. A toddler bed is lower to the floor than a regular bed, which can be safer for your child. However, when your child gets too large for a toddler bed, you can use bed rails to keep him from falling out.
