Baby

Right when you thought the tough decision was already made, you realized that your mini crib doesn’t come with a mini crib mattress. Even the best mini cribs do not include a mattress or simply come with a 1-inch mattress pad.

Choosing the right mattress for your baby crib is a matter of safety. Using the right size mattress can help reduce the risks of Sudden Infant Death Syndrome (SIDS), according to the American Academy of Pediatrics (AAP).

What to consider when looking for the right mini mattress:

  • Firmness: It is recommended by the American Academy of Pediatrics that a crib mattress be firm. It must not conform to the shape of your baby’s head. Look for a mattress between 8 and 10 on the mattress firmness scale. It will also provide better spinal support than a medium or soft mattress which provides more pressure relief.
  • Fit: According to the FDA’s crib guidelines, the mattress must fit tightly around all four sides of the crib base to prevent the baby from getting trapped between the mattress and the crib railings/walls. Always check your mini crib manufacture guidelines for recommended mattress dimensions.
  • Materials: Look for non-toxic crib mattresses, look for options made from materials like wool and cotton. They are naturally fire resistant, not requiring the application of chemical fire retardants to meet safety standards. Natural latex is a good alternative to polyurethane foam and synthetic latex. A good place to start is to go for mattresses that are GREENGUARD Certified. They meet some of the world’s most rigorous third-party chemical emissions standards, helping to reduce indoor air pollution and the risk of chemical exposure.
  • Thickness: Buy a mini mattress of the right thickness for your mini crib you are thinking of buying or already have. Buying the wrong mattress can become unsafe for your child. A mattress that is too thick for your mini crib, it will place your baby too high in the crib and a mini mattress that is too thin could be comfortable for the child. Always check the mini crib manual to find the recommended mattress height for it.
