A Quality Crib Mattress
You need to ensure that the crib mattress you pick is of good quality. It should fit the crib properly, of course, and not hang out over the sides or cause any problems with weight distribution. The child should be able to rest comfortably in the middle of the mattress without risking the mattress slumping over to one side or caving in. The mattress should not be flimsy or old. It should be in good shape, of course, without any odors or aromas that may cause problems. It should also have a good quality fabric casing or else be able to fit a good quality fabric encasement. This is important for the feel of the mattress on your child's skin.
Getting Expert Advice
Another item of importance in choosing the best crib mattress is finding one that is structurally sound for your baby's posture growth. You want to ensure that you have a mattress that will support the baby's back and legs, giving it ample support so that growth is possible in the right terms. With a flimsy or soft mattress, you may risk that the child does not have ample hard support on the back or spinal chord, which may risk improper growth. The child should be able to rest comfortably in all positions as they sleep to allow for this type of growth and enable the proper structuring of the child's bones. Without a proper crib mattress, this structuring may work out wrong.
The best way to find out about a crib mattress for your child is to ask your doctor. They can advise you as to the right brand names and the right sizes for your child so that you know what you are getting into. Some cribs may come with a mattress that fits properly and is adequate, but if not you can buy it separately out of most department stores or sleep stores.
