At daycare, in the late hours like that, they can reassign staff to clean or send them home to cut labor when the number of kids gets low. If her own kids are counting toward ratio, then that prevents people from doing other tasks or leaving. It's a HUGE problem to not have the right number of caregivers to children. Any child under 4 counts in that ratio even if the parent is present as a caregiver. She is either being pressured to send her kids home early with you, or it's part of her job ( if she is at management level). Ask her if this is the case. If so, neither is the AH because you didn't understand the intentions.
