The more realistic answer is that she'd pump the milk and store it for use. You can seal portions of milk into little vacuum bags and keep them in the fridge. When you need to use it, you warm up the bag and put it into a baby bottle, and then you bottle feed the baby with your own defrosted milk.

Saki and Hatsune would be too tired to have much sex. They'd very much be doting, fretting parents. After they've put the baby to sleep in the bassinet, they'd have to stay quiet to keep from waking the kids. Saki would lay down with a book and try to read a bit by lamplight. Hatsune would snuggle into her shoulder and try to catch up with messages but would quickly fall asleep with her phone in hand. Saki doesn't make it many pages before she, too, feels herself succumbing to sleep. She puts Hatsune's phone aside to charge before she lays a peck on her forehead, turns off the light, and snuggles in closer to catch a few winks before the baby wakes up again.

Less horny, more quiet domestic romance.
