According to the American Academy of Pediatrics Childhood Sleep Guidelines, infants should sleep between 12 to 16 hours, while growing toddlers should grab between 11 to 14 hours of shut-eye. That's why picking the perfect crib mattress is key for a good night (and naptime) slumber for your little lamb.

While there are several factors to consider when choosing a crib mattress and setting up a safe sleep environment for your child. Parents should select "a firm mattress that is made for the crib, meaning perfect in size with a tight-fitting sheet," suggests S. Daniel Ganjian, MD, a pediatrician at Providence Saint John's Health Center in Santa Monica, California. "There should be no space between the mattress and the sides of the crib."

And other than a fitted sheet, there shouldn't be anything in the baby's bed, particularly during the first year. "The most common mistake that parents make is putting something in the crib besides a tightly swaddled baby," says Gina Posner, MD, a pediatrician at MemorialCare Orange Coast Medical Center in Fountain Valley, CA. "There should be no stuffed animals, no crib bumpers and no sleep positioners. Just make sure it is a new crib that is up to current standards."

Dr. Ganjian also advises against using an old crib and mattress. "Hand me downs used to be great, but now you really have to watch out for them, since many have been recalled or are dangerous because there is some subtle defect that you might not be aware of."
