Things Consider Before Buying Best Mini Crib Mattress

We are listed some of the best mini crib mattresses and covers in the market, from the best material to quality of firmness to easiest to wash. But before you are ready to buy a mattress you really need to know what crossed the line and make a mini mattress become dangerous for the baby.

Since infant babies are underdeveloped and very sensitive choosing the best mattress out there is very important for the well-being of your baby. Here are some steps you need to know before buying a mattress for your baby.

Firmness of the mattress:

When choosing the mattress you always got to study its firmness. The baby mattress needs to be exceptionally stiff in order for the baby to develop its bones and not risk suffocating.

If you buy a soft mattress for your baby this might increase the chance of your baby suffocating during its sleep and also the bones of the baby do not harden.

Make sure the mattress is breathable and light for your baby to not have any risk of suffocation and trouble breathing during sleep.

There are mattress covers out there that do support your baby’s neck and back while sleeping. We have even mentioned a few on our list of the best mini crib mattresses.

Safety of the Crib Mattress:

Another important thing you should be aware of when picking a mini crib mattress for your baby is the level of harsh chemicals and the level of flammability the mattress has.

In modern days mattresses are created to be toxic-free and anti-flammable, but not all of them are like this. So when choosing a mattress for your baby be sure that these mattresses are tested and approved.

Your baby’s health in the long term is determined by the quality of the mattress, so I recommend you buy an expensive mattress because as the saying goes; better safe than sorry. Apart from that, you want the mattress foam to last long right?

Well, it is best to get the cover water-resistant, anti-mold, and anti-bacterial, this means that if water or if the baby accidentally urinates in the mattress the liquid will not access the foam part of the mattress because if that happens the mattress will smell horrible.

Being anti-mold and anti-bacterial means that the cover is not prone to letting mold form or it does not attach the bacteria onto the surface.

By this, you do not have to worry about the baby getting seriously ill or worse than they will get. Another thing you have to worry about is the size of the mattress in comparison to the crib.

If the crib is bigger than the mattress then you have to stick on the two-finger rule, this is a rule everyone should know about the space between the mattress and the crib.

Simply try to easily put two fingers in the space between the mattress and the crib and it space easily fits two fingers or can probably fit, even more, then this can be dangerous for your baby.

If the mattress does have such a space apart from the crib then the baby could get their limbs stuck inside the space and because of their delicate bones could even get seriously injured.
