ELI5: What happens when a non-fully grown tattooe'd body grows?

Does the ink stretch? Does it get some 'empty spaces' in its pattern?

I'm wondering this since a couple of days, but don't have any knowledge on the matter. May you explain me like I'm five?

Cheers!

The ink of a tattoo continually 'spreads' throughout the life of a person.  As cells divide or die off, the bigger chunks of the pigments/metals in the skin will break apart and generally migrate.  This just results in a blurry/faded tattoo.  That's why tattooed old folks have blurry tattoos.  The human growth isn't usually rapid enough to cause visible separations in the image... but rapid weight gain and pregnancies can do just that.  A stretch mark has the ability to completely ruin a tattoo.
