Part of the reason Kayla opted to remain at home instead of move in with J.R. was so that she could lean on her mother for support...and have a round-the-clock babysitter. Not that J.R. couldn't watch Rylan, but Kayla seemed to have a really hard time letting go of the familiar. And she just wasn't ready to grow up.
Check out the "16 and Pregnant After Show" clip below, where Kayla tells SuChin Pak that she misses her friends--they all recently went on a spring break trip and she obviously couldn't go. She loves Rylan, but wishes she had him later on in life so she wouldn't have had to give up her youth.
