Crib Mattress Bedding Sets And Accessories

85 reference of crib mattress toddler size in 2020 ...

Once youve purchased a crib mattress, there are other things youll need to stock up on, like bedding sets and accessories.

  • Fitted sheet: If your baby is sleeping in a crib or bassinet, you will need, at a minimum, a mattress and fitted sheet, says Witkin. I always recommend having at least two sheets so that when the inevitable diaper explosion occurs during the night, youll have another sheet available immediately.
  • Mattress protector or pad: Since those diaper explosions are basically guaranteed, a waterproof mattress cover can be a lifesaver.
  • Wearable blanket/onesie: As it is not safe for infants to sleep with loose blankets or covers, a wearable swaddle or sleep sack is key, Witkin says. Swaddles that have Velcro or zippers are an easy and convenient solution.
  • Crib:

    There are also items that you should never put in a crib when a baby goes to sleep.

    Babies cribs and sleep environments should be free of pillows, loose blankets, and stuffed animals, advises Witkin. Additionally, you should avoid overheating your baby with too many layers of clothing and a hat. In general, babies need one more layer of clothing than you do to be comfortable.

    While there should be nothing in the crib except for the baby, Witkin notes that the exception to this is a pacifier since its been associated with a decreased risk of SIDS. Avoid pacifiers that clip to clothes during sleep, though.

    How To Choose The Right Crib Mattress Size

    So, you have the best and most beautiful crib for your baby. But what about a crib mattress? Picking the right size is one of the most important features you have to consider when buying a baby crib mattress. Only a crib mattress with the fitting dimensions will provide a safe sleeping environment for your little bundle of joy.

    A crib mattress must fit snuggly into the crib! There should be as little space as possible between the mattresss edge and the cribs frame! Wider gaps increase the risk of injuries and suffocation! So, choose a standard-size crib mattress for a full-size crib, a crib mattress with smaller dimensions for a mini crib, and a right portable crib mattress for a Pack N Play or travel crib.

    1. Are the dimensions of all standard-size mattresses the same?

    Yes, as the name standard size crib mattresses tells by itself, are their dimensions standardized. A very small size deviation is allowed, but in general, we can say that the size of all full-size crib mattresses is the same.

    2. Is there a one crib mattress size for mini cribs too?

    No! You have to be a little more careful when choosing a mini crib mattress. Check up thoroughly if the mattress dimensions correspond to the interior size of your crib to fit snuggly into it.

    The right crib mattress size is not the only thing you have to consider when buying a crib mattress! We have made a crib mattress buying guide, where you can find everything you need to know when buying a crib mattress.

    Lie Your Baby Down To Sleep On Their Back

    Lie your baby down to sleep in their crib on their back, rather than their front or side, to greatly reduce the risk of SIDS. Once your baby can roll independently, even if they roll onto their front side as they sleep, they can find their own sleeping position and change positions if the one they’re in infringes on their breathing.

    Standard Crib Mattress Size

    According to the US Consumer Product Safety Commission or CPSC, full-size crib mattresses follow a standard dimension of at least 51 ¼ x 27 ¼ x 5 inches.

    This snuggly fits the interior measurement of a full-size crib which is around 28 in width x 52 in length.

    The narrow gap between the crib and the mattress lessens the likelihood of head entrapment and suffocation should the baby roll over to the side. A standard crib mattress can last you for at least 18 to 24 months.

    Non-full size baby cribs do not follow a standard measurement as they vary in shapes and proportions.
