Most playards are designed for children who are less than 35 inches tall and weigh less than 30 pounds, although some have higher height and weight limits. Many babies exceed these limits before they’re ready for a toddler bed, which is why playards aren’t always a permanent replacement for a crib. Additionally, once your child starts climbing the playard, it’s time to put it away. Playards are relatively lightweight, and a child could tip it while trying to climb out.
