WARNING - THIS MAY BE SCARY FOR SOME.

The newborn screening card can also be used to identify your child (by their DNA) should anything untoward happen to them. It may be the only source of DNA for your child if nothing else is available, especially if the child is very little or there is a significant time period between the child disappearing and the discovery of their body.

Jaidyn Leskie's body was identified using this method (DNA sequencing from newborn screening card).

In a way, keeping the card indefinitely may actually help some people, in the most difficult of situations.

I don't mean to scare anybody, but I personally think it's a good thing.
