Well, it's like this

 Carrie kept talking about (her stepmother) Gabby's photo shoot, which her Grandy (Betty) couldn't help but chuckle.

"But..but honey, she's going to have a baby," Betty squinted.

"Well, she's been planning it for a long time," Carrie hugged herself as if she knew everything going on with her stepmother.

"Is it a new job?" They were busy at the dining table. Carrie was drawing while Betty was cutting out some simple patterns for Barbie clothes she'd found on YouTube. Hopefully, they would fit Carrie's favorite purple-haired Barbie.

"No. She only has the one job she goes to every day of the week except Saturday and Sunday."

Naturally, Carrie was very informative while she colored all over the page with her purple crayon.

Betty nodded. She knew this. Carrie's father, Oliver, taught at the elementary school, and these days Carrie spent her days with Betty. 

"Are you in this photo shoot?" Betty wondered how expensive this would be, but these days, maybe a friend was taking photos of  Carrie's pregnant step-mom.

"No, it's just for her and my baby brother."

Carrie liked the idea of a baby brother more than Gabby. This much Betty knew. Gabby was crushed when she found out they were having a boy instead of a girl, but evidently, she was making the most of her pregnancy, especially documenting her pregnancy with a photo shoot. Something Betty had never thought of doing during her days of early motherhood.

Of course, back then she might as well have been on a soap opera in so much turmoil. It was amazing she'd gotten this far. Something she hoped no one in her family had to go through. Of course, her girls went through their own drama, too. But none of them had time for a photo shoot while they were pregnant. It seemed these days everything had to be documented on social media.

"Your Dad's OK with it?" Betty couldn't help but ask as she started handsewing a sweater and shorts from some of Carrie's little leggings for Barbie's outfit.

"He didn't say," Carrie shrugged. 

"It seems to me he should be in those photos."

"He's at work."

"Yeah, he's working, all right." Betty found herself sighing. Gabby had a good office manager job at City, but she liked to spend money too. The things on her list at the baby shower were quite expensive and they still lived in her two bedroom apartment. 

"Nobody's got time to clean anything, lately." Carrie looked up at her.

"Oh, really." Betty practically rolled her eyes. She guessed she'd have to make a surprise visit.

"All the clothes are on the couch. You can't even find it." Carrie told her.

"I see." She guessed she could start prepping meals, and Oliver's dad could help with tidying up the place.
