Pregnant Belly Casting

A belly cast is a three-dimensional plaster sculpture of a woman's pregnant abdomen as a keepsake of her pregnancy. It can also be known as a belly mask, pregnancy belly cast, a pregnant plaster cast, or prenatal cast.

Belly casts are most often made toward the end of the third trimester of pregnancy, though a series of casts may also be made during the pregnancy. They are made by preparing the skin with a coating of Vaseline or a similar lubricant and adding strips of wet plaster gauze over the abdomen to make the cast. 

Some women also cast their breasts, arms, hands and thighs into a full torso sculpture. The plaster sets in about 20–30 minutes but some fast-setting strips set in five minutes. Once set, the cast is gently removed by the mother using a wriggling motion. It takes one or two days for the cast to dry completely.

Most pregnant women make their casts late in pregnancy (36-39 weeks) to capture their bellies at maximum size, while some make a series of casts to track their growth. When you do your cast is up to you!
