I am a parent to adult 'children'. I would appreciate any wisdom that can be shared.

My youngest and his wife delivered a healthy, normal weight baby on their due date, but on the first full day at home, the baby started having difficulty keeping her oxygen level up (she would turn bluish). They took her to the ER, where she actually stopped breathing. Unfortunately, although she had nearly every test known to man, they never came up with a reason why she stopped breathing. She was discharged after 12 days, most in intensive care.

Since then, my son and daughter-in-law have been hypervigilant, and are definitely not enjoying being parents. "What if...?" is the main thing on their minds.

Are there any studies that deal with how to help new parents who have experienced a newborn's near-death experience to enjoy their baby more?
