What is the Standard size of Crib Mattress?

Babies spend about 18 hours sleeping in a day, more like they spend the whole day sleeping (well, apart from waking up at intervals to eat or play a little).

You can’t possibly carry your baby for 5 hours straight, talkless of 18 hours, hence you need to get sleeping aids for them.

Mattresses alongside baby cribs have served as sleeping aids for babies over the years. However, babies are very delicate, and it is important to get the right sizes of cribs and mattresses for them.

The issue of how to choose the right size of crib mattresses for babies is a common one amongst nursing mothers, particularly new ones.

It is important to be double sure of the dimension of your crib before selecting a befitting crib mattress.

To be sure, measure the length and width of your crib and let that determine the size of the baby bed you’ll buy. As a rule, the space in between your mattress and the crib should be just enough to fit 2 of your fingers or less. Anything more is not safe for your baby.

Which Size of Crib Mattress Do You Like!

The type of crib mattress you choose to settle for depends on your preference and of course, your pocket, however, you should also consider the following before making a choice :

  • The firmness of the mattress- The mattress does not have to be hard, however, it should be firm enough to prevent your baby’s head from sinking into the mattress.
  • Presence of Waterproof covers.
  • Certification by appropriate authorities.
  • Breathability.
  • The mattress should not be too thick or light. The thickness should be just perfect.
