Where like, all Time Lords were expected to be disinterested and logical when it came to rearing their children. Heavy on the rules and lessons but any affection was frowned upon. Except the Doctor’s mother just really sucked at that.

Like she would be walking home through the corridors of the Citidel slowly and stately. Face a mask of composure lest anyone suspect. But then once she got to his chamber and the door was closed she’d just rush to his crib and scoop him up.

“Come here baby. Mummy’s home. Did you miss me? I missed you. Yes I did. I missed my little Theta.”

And she’s got his robe off in seconds and is pressing her face into his fat little baby tummy as he squeals.

“Who’s got the cutest little toes? Who’s got the cutest little toes on Gallifrey? My baby that’s who. I just want to eat them up. I want to eat your little toes right up nom nom nom.

And then she would snuggle him and nurse him which she wasn’t supposed to do. And sure she felt a little guilty, and prayed she wasn’t messing him up too much with such an unseemly display of maternal affection. And she well knew what the Gallifreyan mommy blogs would have to say about something like this.

But then he’d make the cutest little cross eyed face when he farted and she just couldn’t help herself. He was too precious. He was hers.
