A baby bump is fun, but it takes only a backache or cankle to turn it into a grind.

Push through the trimesters with Oh Baby shampoo and conditioner from local beauty brand Nine Naturals. The chemical-free products are specifically designed for moms-to-be.

Each vegan-certified formula contains nine ingredients, including organic aloe (for moisturizing), vitamin B5 (for luster), and wheat protein (for strength). Its fresh peppermint-rosemary scent sticks around long after bathtime ends.

A line of body and baby products are in the works.

It’s worth getting lathered up about.

Available at Bellybum Boutique, 4347 North Lincoln Avenue, at Pensacola Avenue (773-868-0944 or bellybumboutique.com); Belly Dance Maternity,  1849 Greenbay Road, between Central Avenue and Elm Place (847-926-0053 or bellydancematernity.com). To see products, go to ninenaturals.com.
