It's been a while since we last checked in with 16 and Pregnant's Brooke Smitherman-Tarrant and her growing family, but girlfriend is doing better than ever! She and husband Cody just welcomed their daughter Ryley Jean on Dec. 18, 2012, and she's already a little model in training.

Brooke entered the 5-month old bundle of joy in a photo contest on Parents.com for the chance to land her very first gig as a covergirl.

"Will everyone please click this link and vote for Ryley we would love to see her on the cover of parents magazine!" she wrote on Facebook on Monday, May 20, along with an adorable picture of Ryley wearing a pink, teal, and leopard-print onesie with a matching bow and huge smile.

On Tuesday, Brooke updated fans that she was in ninth place — and by Thursday, she'd already jumped up a spot to No. 8!

"She is in 8th today! We REALLY need your help please Vote Vote Vote!!!!!" Brooke urged her followers.

Ryley's obviously the cutest baby around (OK, fine, we might be a tad biased), so head over to Parents.com to cast your vote and share with all your Facebook friends!
