You should lower a crib when your baby can stand up or pull themselves up to a standing position.
Why Lowering the Crib is Important
Lowering the crib mattress is a crucial safety measure to prevent your baby from falling out. Once your child can stand, even with assistance, they are at a significant risk of climbing or falling over the crib railing. As Dr. O'Connor noted, a crib mattress that is too high poses a serious fall risk.
Key Indicators to Lower the Crib:
- Pulling Up: When your baby starts using the crib rails to pull themselves into a standing position.
- Standing: If your baby can stand unassisted in the crib.
- General Mobility: Even if your baby isn't standing consistently, increased mobility and attempts to climb are signs it's time to lower the mattress.
Crib Safety Guidelines
It's always better to be proactive when it comes to crib safety. Here's a general timeline and best practices:
| Stage | Action | Reasoning |
|---|---|---|
| Newborn to Several Months | Crib mattress at highest setting | Easier to reach and lift the baby in and out of the crib. |
| Baby starts to sit up | Consider lowering one level | Lowers the center of gravity and gives the baby less leverage to pull themselves up. |
| Baby can pull themselves up | Lower to the lowest setting | Prevents climbing and falling out of the crib. |
What if the Crib Doesn't Lower?
If you have an older crib that doesn't have adjustable mattress heights, it might be time to consider purchasing a new, safer crib that meets current safety standards.
