"Oh look my head," flop.

"I guess baby Jeremy can't pick you up either, you're too little!"

"He could try," she says, "I don't mind."

"Jeremy, you can try to pick up Catherine!"

Jeremy, being a newborn, does not do this. He looks at Catherine and shrugs dramatically. 

Giggle.

A few days later he says to his wife, "I want to tell Catherine about how she was born and found, I worry if we wait too long it'll seem more like - a terrible secret instead of something that we've always been quite all right with -"

"You think she's old enough to follow it? I don't even remember being her age..."

"She's a bright kid. Maybe not the whole story, but 'Mama had Catherine and then she met Papa and he loved them both and took them home,' yeah, I think she'd follow."

"Yeah, all right."

"When I first met you," he tells Catherine, "you were two months old! Bigger than Jeremy already. You were a very quiet baby."

"Could I hold my head?"

"Mostly. Which was good, I didn't know how to hold a baby."

"Could you not have holded me if I was so small?"

"Maybe not. Maybe your mama could have taught me."

"Teach meeeee I want to holllllld himmmmmmm."

"I was bigger than you! - maybe we can find a doll that is Jeremy-sized for practicing with, how about that?"

"And then I hold him?"

"If you can be safe with the doll."

Nod nod.

He fetches a blanket and transfigures her a tiny baby-Jeremy-sixed blanket with a floppy neck.

Catherine studies her mama's Jeremy-holding carefully and cradles the blanket just so mostly.

He corrects blanket-grip where necessary.

Hold hold hold "now pleaaaaaase?"

"Okay. Veeery careful, right?"

"So, so careful."
