Safe to hold baby without supporting head?

Just curious how you know when it’s safe to hold a newborn without supporting their head? I have a 3 1/2 week-old so I’m not expecting it to be soon. I’ve found a lot of stuff on head control milestones but nothing that tells how you know when it’s safe to hold YOUR baby upright without supporting their head...
