They’ve already got your kids dna if your kid was born in the past 10 or 15 years:

In 10 more years they’ll have DNA for everyone under 25 born in this country. Roughly 1/3 of the population at that time.
Plus everyone ‘arrested’ for any reason and anyone who’s ever been in the military or reserves.
I remember when you did not need a Social Security Number until you started working. Now when a child is born a number will be issued.
When do I have to apply for a Social Security number for my newborn?
Answer:
There’s no time limit on applying for a Social Security number for your newborn. However, you may want to do it right away, because you’re required to include a child’s Social Security number on your tax return to claim that child as a dependent.
