How long can a child use a travel crib?

Most travel cribs are rated for children up to roughly 30 lbs or 35 inches, or until they can climb out. Specialist parenting subreddits repeatedly note that tall toddlers around 18-24 months may start climbing out, which renders any travel crib (even a $380 premium one) effectively unusable. Plan your purchase around how many travel years you'll realistically get.
