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:

  • The firmness of the mattress- by firmness, I don’t mean 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.
  • The mattress should not be too or less thick.

Ultimately, I can only make suggestions and help you to know what to look out for, but the rest is up to you. You should bear in mind that the dimension of your crib determines the size of crib mattress you will choose. However, no matter what you decide to go for, don’t use old crib mattresses for your babies, their safety is not guaranteed.
