Lowering Crib Mattress to Floor (Step-by-Step Guide To Keep Your Baby Safe)

Lowering crib mattress to floor is a common issue among parents with a little climber who’s not yet ready for a toddler bed.

I have a little cheeky monkey myself, and when she started climbing out of her crib when she turned one, I felt like I had no choice but to transition her to a floor bed.

But it was a very hard, and very frustrating transition.

So if your little one is not yet ready to get out of the crib but not yet ready for a floor bed either, a lowered crib mattress on the floor inside the crib is your best bet to keep them safe.

But is it really okay to lower the crib mattress on the floor? You’ll find out in this article.

Lowering Crib Mattress to Floor: Is it Really Safe?

Lowering a crib mattress to the floor inside the crib is a practice that parents consider when their kid is attempting to climb out of the crib but is not yet ready for a toddler or floor bed.

It’s safe if done right and it can become your safest bet in keeping your little one inside the crib.

When To Lower Crib Mattress Setting

There are two stages to look out for if you’re wondering when you can lower the crib’s mattress setting.

The first is when your baby starts sitting up. 

It’s a good time to lower the mattress to the middle setting as this prevents them from accidentally falling out.

That’s a sign for you to adjust the crib’s mattress to the lowest setting. This keeps them secure as they explore their newfound standing skills.

How to Lower Crib Mattress to the Floor Inside the Crib

Transitioning your baby’s crib mattress to the floor inside the crib can provide a cozy and secure sleep space as they grow. Here’s a step-by-step guide to help you make this adjustment safely and effectively.

Step 1: Check the Crib Design

Before making any changes, ensure that your crib is designed to allow the mattress to be placed directly on the floor. 

Some cribs have adjustable base supports that can be removed or set to the lowest position to accommodate this change.

Step 2: Remove the Base Support

If your crib has an adjustable base support, carefully follow the manufacturer’s instructions to remove it. 

If you’re not handy with tools, better ask your spouse or hire someone to do this for you.

Step 3: Ensure Proper Ventilation

To promote airflow and prevent moisture buildup, consider placing a firm and flat surface, such as a thin mattress or a piece of cardboard, under the crib mattress. 

This will help maintain a comfortable and hygienic sleep environment for your baby.

Step 4: Adjust Bedding and Surroundings

Once the mattress is lowered to the floor, make sure the bedding and surroundings are safe and comfortable. 

Avoid using soft and fluffy bedding items that could pose a suffocation risk. You might want to place a soft rug or playmat around the mattress to create a cushioned area.

Step 5: Test for Stability

Gently press down on the mattress in different areas to ensure that it’s stable and securely in place. This will help prevent any shifting or movement during your baby’s sleep.

Step 6: Regular Check-ins

As with any changes in your baby’s sleep environment, it’s essential to monitor how your baby responds to the new setup. 

Regularly check the mattress’s positioning and your baby’s comfort to make sure they are sleeping soundly and safely.

How to Put Toddler into Lowered Crib Mattress On The Floor

Putting a sleeping toddler into a lowered crib mattress on the floor can be quite difficult and not ideal.

So the best thing that you can do is to put them in the crib awake. Or slightly drowsy.

Tell them beforehand why you need to lower the crib mattress to the floor and what the new sleeping arrangement for them will be.

Guide them gently onto the mattress and encourage them to lie down comfortably.

Risks of Putting Crib Mattress on Floor Inside the Crib

While placing a crib mattress on the floor inside the crib can offer certain benefits, it’s important to be aware of potential risks and considerations. 

Here are some risks to keep in mind:

  • Airflow and Moisture

Placing the crib mattress directly on the floor can restrict proper airflow around the mattress. This might lead to moisture buildup between the mattress and the floor, potentially creating an environment conducive to mold or mildew growth. Adequate airflow is essential for maintaining a healthy sleep environment.

  • Hygiene and Cleanliness

With the mattress near the floor, there’s an increased likelihood of dust, dirt, and debris finding their way onto the mattress. Regular cleaning and vacuuming of the floor become crucial to ensure that the sleep space remains clean and hygienic.

  • Temperature Regulation

Elevating the mattress slightly off the floor can help with temperature regulation. When placed directly on the floor, the mattress might absorb the cooler temperature of the floor, potentially causing discomfort for your baby.

  • Accessibility

While a mattress on the floor can make it easier for toddlers to get in and out, it might be more challenging for parents to reach down and pick up their baby or toddler. This could lead to strain on your back or other discomfort.

  • Safety Concerns

Depending on the design of the crib, placing the mattress directly on the floor might create gaps or spaces between the mattress and the crib’s sides. These gaps could pose safety risks, especially if your baby rolls or moves around during sleep.
