A convertible crib is a wooden, acrylic, or metal baby crib, which grows with your child. Meaning the crib transforms into bigger beds along with the child’s growth.
Standard size baby cribs are full-size cribs of different types and models. Depending on the type, model, design and thickness of the material cribs are made of, overall external measurements of those cribs are not the same. Another story is with inner measurements, as they are the same for all full-size cribs.
