Her mom carries the new human pup with her everywhere, and when the wolf-dog pup starts tumbling after them she laughs and carries that pup along, too.
She's off from missions while on maternity leave, so the pups can have the experience of being hauled to clan meetings and councils - they're a bit of a pain but the look on everyone's face at having to deal with her is worth it - and training. She considers getting a genin team, and chuckles at the thought of training them with a baby on her back.
Sounds fun, and it'll effectively extend her leave, so she signs up for the next graduation.
Kiba's getting too big to think being carried everywhere by his mom's neat. He instead runs about with the pups his age, toddling in and out of trouble at quite impressive speeds.
She talks to the pups, too, nearly constantly, and her nin-dog Kuromaru teaches both the dog tongue.
She notices gradually that the wolf-dog pup seems to have slowed down on aging after leaving 'entirely helpless', shrugs, figures who even knows with nin-dogs and nin-wolves-who-might-be-gods.
Tsume also turns over names in her head, eager for her baby's first word - when the pup will be officially brought into the clan, and granted a human name.
