Infant Safety – Why the Crib Mattress Height Matters

The level of the crib mattress directly affects the baby’s safety, especially when they start gaining new motor skills. In the first months of a newborn’s life, having the mattress at the highest level facilitates care. However, once the baby can lift their head, sit up, or crawl, it is necessary to adjust the mattress height to their current needs.

Parents often wonder when to lower the crib mattress to ensure adequate protection. Experts recommend making this change when the crib’s railings are no longer high enough compared to the child’s motor abilities. This is particularly important when the baby can pull themselves up by their arms or stand. In such cases, a mattress set too high can lead to many dangerous situations.

Parental Convenience – How Mattress Adjustment Improves Care Comfort

An infant crib with a properly adjusted mattress significantly facilitates comfortably lifting the newborn and putting them to sleep, minimizing the need to bend excessively. This makes activities such as feeding or changing diapers less straining for the back and joints. Proper adjustment allows the furniture base to be adapted to the changing needs of both the adult and the child.

When to Change the Crib Mattress Height? Child Development Stages

Adjusting the mattress height in the infant crib should align with the child’s developmental stages. Here are some tips to help parents properly assess the right time for adjustment:

1. Newborn and first months

The mattress should be set at the highest level, providing comfort during diaper changes and feeding, while minimizing the need to bend deeply.

2. Infant (about 4–7 months)

When the baby starts lifting their head independently, rolling onto their stomach, or sitting up, the mattress level should be lowered. At this stage, there is a higher risk that the child might pull themselves up to the crib edge and fall out.

3. Child around 7–9 months

When the baby begins to kneel or attempts to pull themselves up by their arms, the mattress should be at the lowest level.

4. Older infant (over 9 months)

For babies beginning to stand, the base must prevent leaning over the railings.

Every child develops at their own pace, so instead of strictly following age guidelines, it’s worth basing decisions on observation. Regularly monitoring your child’s activity allows for quick responses to ensure a safe place for rest and play.

Technical Tips for All Parents

Choosing a crib for your infant is a decision that affects both the baby’s safety and the parents’ comfort. How to take care of this? It’s important to ensure that the mattress level setting is appropriate. To check, pay attention to the distance between the mattress surface and the top edge of the crib rails. The height should allow the child to stand and sit freely while preventing the risk of leaning over the rail. Regular monitoring of the baby’s motor skills will help determine the right time to lower the mattress.
