‘CBS Schoolbreak’ has a lesson for siblings: Help bring up baby

“Two Teens and a Baby,” the title of a new CBS Schoolbreak Special, brings to mind a story of high-school pregnancy. But in this case, the two teens are the baby’s siblings--not herparents--and the story is about how the new addition affects them.

The tale begins when brothers Brian and Chris learn that their mom is pregnant. Both boys experience reactions to the news: Chris realizes he will no longer be “the baby” of the family, while Brian learns his free time will be curtailed. The adjustment proves to be uncomfortable--until both boys learn to accept their new roles and enjoy their infant sister.

“CBS Schoolbreak Special,” Tuesday 3-4 p.m. CBS. For 11- to 17-year-olds.
