Adorable Adult Cake Smash Photos Put the Fun in Growing Up Photograph raises the question "Why should kids have all the fun?"

 -- When photographer Amiee Berry's friend came to her asking for a photo shoot for her 30th birthday, the two women put their heads together to come up with an original idea.

Then they put a crown on one of those heads and added a cake, a tutu and an "about me" board.

The friends decided to turn the cake smash photo shoot -- practically a rite of passage on a baby's first birthday -- on its head.

"Why should kids have all the fun?" Berry asked.

Berry, a mother of two from Forney, Texas, told ABC News that her friend Jackie Slinkard -- also a mom of two young children -- wanted to put a fun, positive spin on her upcoming 30th birthday. The only obvious difference between adult cake smash photos and a baby session, it seems, is the age of the model. Oh, and a bottle of bubbly.

"It's a new milestone that deserves to be celebrated," Berry said. "Often turning 30 has a negative connotation. But Jackie wanted to depict this new phase of her life."

The photos, Berry said, have been viewed more than 2 million times and shared thousands since she posted them to Facebook on Monday. Berry said the reaction has been overwhelmingly positive.
