If the guy who sculpted Mount Rushmore could turn a plain old mountain into a national treasure, then you shouldn’t be afraid to declare your pregnant belly a work of art.

Cast your fears aside with a belly casting from It’s All About the Belly.

First, schedule an appointment for a belly molding expert to capture your bump. Once the mold has dried (24-48 hours), they sand and paint it. What happens next is up to you. Have your shower guests sign it, decorate it to match the nursery, or let baby’s siblings add their handprints.

Recommended for expectant mamas 30-34 weeks, the process is painless (think papier-mâché) and quick (around 30 minutes).

Modest mamas can order a DIY kit. Either way, you’ll have a permanent memento of your landmark shape.

Captured at its peak.
