Imagine your OTP being woken up in the middle of the night by their baby crying. Person A is usually the one to take care of the child during the night but Person B can see how tired they are and kisses their forehead before telling them to go back to sleep and getting up to take care of the baby.
"Cora," Robert muttered, still half-asleep, "baby's awake."
When he received no response from her, and heard another insistent knock on their bedroom door, he nudged her shoulder a bit harder, saying "Cora," again as he did so. It was quite dark in their bedroom so late at night, but when Cora stirred awake a few seconds later, drawn from sleep by his nudges, he could tell even without seeing her face that she was displeased.
"Why yes," she muttered under her breath. "The baby is awake again. Fancy that." He felt her roll out of bed and pull the covers back in one turn. Trudging across the floor, he listened until she opened the bedroom door, inviting a sliver of light from the hallway into their room, and took a squalling Mary from the nurse's arms.
Robert attempted to close his eyes again as Cora returned to bed with the baby—for there was not all that much he could do to help with this particular task—but he was kept up by the rhythmic sucking noises Mary made as she nursed just a few inches from his head. He tossed and turned a few times; well perhaps more than a few, as Cora sighed in annoyance after the third turn, but was unable to get comfortable.
When Mary finished nursing a handful of moments later, he thought he would finally be successful but still, sleep would not come. Robert listened once more as Cora patted their daughter's back, and he listened as the baby let out a soft burp after a moment. He felt Cora sit up more fully, likely to get up and put Mary into her bassinet, but just as she moved, Mary began to cry again.
And to Robert's utter bewilderment, Cora began to cry as well.
"Darling?" He said, sitting up and attempting to light the candle on his bedside table. But Cora only cried harder, choking out "I…am…so…tired," between sobs.
Getting up out of bed, as sleep was certainly not on the horizon now, Robert crossed the room and took Mary from his wife's arms before she could protest the matter. Leaning down, and balancing Mary with one arm, he pressed a kiss to Cora's forehead and said simply, "sleep."
Cora continued to cry, but replied, "thank you," in a quiet whisper as she wiped at her eyes and watched her husband smile, disappearing into his dressing room with their fussy baby.
Robert, for his part, was only slightly concerned at having Mary all on his own. She was nearly four months old, so more solid than she had been at birth, but he was still terrified to make a mistake. The safest course of action seemed to be to relax atop the small dressing room bed, with Mary in his arms. He rocked her, murmuring in a low voice to sooth her, and told her all about the estate and his plans for the coming day. She fell asleep pressed to his chest, and when he awoke a few hours later, she was still fast asleep in much the same fashion.
He couldn't think of a more wonderful way to wake up.
