A Little Tenderness
Severus sat with Charlotte until she calmed down enough to fall asleep. When he looked over at Hermione, he noticed she too had fallen asleep.
Too tired to bother replacing Charlotte in her crib, Severus considered magicking her in but decided against it- flying through the air would certainly wake her up as well as scare her.
The next best thing was to cradle her in his arms, lie down, and close his eyes. He only hoped neither Hermione nor him accidentally rolled over onto Charlotte during the night.
Hermione would surely kill him if he allowed that to happen.
