About DC CUPCAKES: BABY CAKES:

Katherine's having a baby!! It's one emotional and physical roller coaster after the next when Sophie, Katherine and Mommy plunge into the reality of Katherine's pregnancy. Exhausted andburdened with a huge belly, Katherine can barely lift a finger as Sophie works round the clock to plan the ultimate baby shower for her younger sister.

While Sophie is determined to build the most beautiful Rubber Duck out of cupcakes for the big event, Katherine can't wait to find out the sex of her baby at her shower thanks to some very special cupcakes! And Mommy is not to be outdone when she gives Katherine an unusual gift - a very fussy, lifelike doll that grades Katherine on her parenting skills.

On top of everything, the sisters are taskedwith building a larger than life globe made of cupcakes for the opening of the National Children's Museum. With not one, but two massive cupcake builds, a baby doll and a big belly... there is never a dull moment in this action packed special that takes viewers along Katherine's journey through pregnancy and the birth of her baby.
