Rebar (wood) spacing must not exceed 2 3/8 inches. The mattress should be very strong and should not sag under the baby's weight. It should be close together and there is no gap between the wall of the crib.
The top of the crib rail should be at least 26 inches from the top of the mattress. When your child gets taller, lower the mattress regularly.
The headboard and pedals should be solid with no decorative cuts. Corner posts that may cause injury or hanging should be removed. Do not use a crib with an armrest. These things are not safe.
Crib bumpers (or cushions) seem to help protect the baby from airflow and impact, but not in cribs. There is no evidence that bumper pads can prevent serious injury and they pose a risk of suffocation, suffocation or pinching. In addition, older babies can use them to climb out of the crib.
Put big toys and plush toys on the outside of the crib, because your baby might use them to lift the legs up and over the railings. Pillows, heavy quilts and heavy blankets are not part of the crib; babies can suffocate under them.
Keep the crib away from the window, and direct sunlight and airflow can make your baby uncomfortable. If placed close to the radiator, the crib will become very uncomfortable. Also, make sure there are no ropes around the blinds or curtains that can wrap around the baby's neck.
Once your child is about 3 feet tall, he should start sleeping in bed. If you are worried that he is falling from the bed, you can start with the mattress on the floor.
Put a sturdy mattress on your baby's crib and make sure there is no space between the mattress and the crib wall. Your baby should not sleep on waterbeds, sheepskins, pillows, sofas, armchairs or other soft surfaces. Thick blankets, duvets, quilts, pillows, and large, soft stuffed toys should not be used in cribs; it can easily suffocate if the baby is trapped under heavy bedding or when his face is pressed against the pillow.
Babies do not need extra support, such as rolling blankets or commercial equipment. A cumbersome material like this can make a crib messy and can be dangerous for a baby.
