A common and touching design you often see is to simply take the footprints of your baby that they make at the hospital and have them transferred to your body. This option has the added benefit of guaranteeing no one else will ever get the exact same tattoo as you. Another common idea is a variation on the Tree of Life theme, working your family names into the branches of a stylized tree. Of course, the traditional name in a banner wrapped around a heart will always show up, as well as the names of your kids being strongly lettered along the forearms. One of the more fun ideas I saw, albeit on a mom, was a Cat in the Hat drawing, with the kids' names taking the place of Thing One and Thing Two, with a Thing Three added in for good measure.
Having a daughter named Olive expanded my design options and I chose a detailed drawing of an olive branch with her birth date printed in small Roman numerals. The end result looks like a drawing you might find in an old naturalist's field guide, with the Roman numerals echoing the plate number of an engraving.
