If you enjoy burning candles, or you have a friend who does, here's a fun little gift. Childish Clothing has a votive set with different scents for every trimester of your pregnancy. They say they're "filled with a heavenly blend of pregnancy-specific 100% certified organic essential oils."
They're made from natural and soy wax with no artificial fragrances or perfumes so no worries there. The only thing we'd like to know that they don't really disclose- what are the scents?
They also have a boy candle, girl candle, and baby candle which come in large glass containers that can be used after your candle burns down. They're all available over at Childish Clothing.
