Most baby playpens on the market are designed for children aged six months and up. Some brands, however, make playpens specifically for newborns that can be used from birth. It's important to choose a baby playpen that is appropriate for your child's age and development stage.
When shopping for a baby playpen, always check the weight and height limits recommended by the manufacturer. A newborn playpen should have low sides so that your baby can't roll or crawl out. The mesh sides of the playpen should be close enough together so that your baby can't stick their head through and get stuck.
Once your baby starts to crawl or pull up to standing, they will need a bigger playpen with taller sides. Look for aplaypen with an adjustable height feature so that you can extend the sides as your child grows. Most importantly, make sure the playspace is large enough for your little one to move around freely and safely explore their surroundings.
