A Little Sister

Linda's POV:
"PHINEAS! FERB! CANDACE!" I yelled. "I HAVE SOME NEWS!"

My children and my stepson ran down the stairs.

"Yes Mom? Yes Dad?" Phineas asked.

"Well, in about 9 months, the three of you will have a younger brother or sister!" Lawrence asked.

"REALLY? Oh mom this is awesome!" Candace gasped.

Phineas and Ferb just looked at each other.
