Some people may think that firm mattresses can be uncomfortable for babies. For their information, an overly soft mattress suffocates the baby. Plus, it also hampers the growing bones of infants. So, the firmer the bed will be, the better it will be. Check that the mattress has infant use ratings.

3. Materials

Infants sleep almost all the time of the day, so their mattress material should be organic and natural so that babies can grow up healthily. Buy those mattresses which are free from any harmful chemicals like BPA or Led.

4. Suitability

The mattress should be fitted into the crib tightly. So, that the baby can’t pull out the sheet or put their hands on the edges of the crib. For checking this, use the two-finger test” method. Stick your two fingers between the gap between the mattress and crib. If there is more gap, then change your mattress.

5. Safety Systems

On the crib, while the baby will sleep, keep all toys, plushies, and other things outside. It may suffocate your kid while they will be in dreamland. Plus, be careful that the bedsheet is tucked well into the mattress, so the baby can’t pull that out.

If your mattress is waterproof or water-resistance, it will be much better. Moreover, be mindful about how taller your crib is. When the infant will grow gradually, they may climb on the crib and fall. So, set the crib as low as you can.
