A/N: I know Jesus and Mariana's sister isn't born yet and her name isn't yet revealed, But I had an urge to do this and this is a fiction for crying out loud! This is just about how their little sister grows up in the Adams-Foster family. Enjoy!

Four-year-old Isabel crawled out of bed and tip-toed to Stef and Lena's room. She climbed on to the bed and sat on top of Stef who was sleeping. ''Mommy?'' Isabel whispered trying to shake Stef awake. ''Our daughter's awake'' muttered Stef. ''I can tell'' replied Lena. ''Mommies!'' Isabel said a little louder. Stef chuckled and sat up to put Isabel on her lap. Her eyes met with Isabel's wide chocolate brown ones. ''Hey,beautiful'' Lena said while sitting up.. ''Did you sleep well?'' asked Stef smoothing her hair.

''uh-huh'' Isabel nodded, ''Can I have waffles?''

''Don't you think you want to wake up your brothers and your sisters first?'' asked Stef.

''No. Jesus gets grumpy when he wakes up'' she said.

''Ok,then'' she laughed, ''Wake Callie up''

Isabel rushed to Callie's room and jumped on her bed. ''Callie,wake up!'' she cried. Callie was half awake. She grabbed Isabel by the waist and tickled her. '''Morning, munchkin'' said Callie. ''Callie!'' Isabel giggled. Callie carried her like a football with her right arm and started walking downstairs. ''Callie, can you take me to the park today?'' she asked.

''Not today, Iz'' she replied, ''I have to volunteer at the foster center''. ''Oh'' replied Isabel.

Later that day, Callie picked up Isabel from school and took her to the park. Callie liked hanging out with Isabel because it kept her mind off of things like the trail against Daphne's daughter's ''kidnapping'', and Isabel was one of the people that cheered her up.

At home, Isabel walked into the garage and saw Brandon playing on his piano. She walked over to him and watched his fingers danced on the keys. ''Hey'' Brandon looked up at her and patted his lap, ''Wanna sit right here?''. Isabel nodded before he sat her on his lap. Brandon showed her the solo to the song he was playing on the piano and she followed by pressing her index fingers on the keys. Brandon didn't mind having Isabel around while he played because she was usually quiet and listened to him play. Callie walked in and saw the foster brother and sister play piano.

After Isabel was put to bed, Jesus and Mariana walked out of her bedroom and talked in Mariana's room. ''Do you think she'll know that Anna's our real mom and Mike's her dad?'' asked Mariana.

''She probably won't remember'' replied Jesus, ''She was just born when Moms adopted her''

''But she's going to know sometime soon'' explained Mariana, ''probably when she's a little old enough''

''We're not going to tell her''

Isabel walked in dragging her blanket in her hand. ''Iz,what's the matter?'' asked Jesus.

''I can't sleep'' she quietly replied.

''Ok, you can sit in here with us'' Jesus said before sitting Isabel on his lap. Isabel snuggled in his embrace and hugged her blanket. After Isabel was adopted, Jesus and Mariana made a promise not to be as absent in her life as Anna.
