When Daddy and Little Don't Agree on Bedtime

So, hi everyone! I hope you can help me out here. I'm 35, been with my partner for five years now, and we've been doing a lot of DDLG lately. It's really fun to explore the roles together, but there's this one thing that keeps coming up that has us both scratching our heads. I used to be very much the little girl in this dynamic. My partner enjoys taking on the role of my caregiver and daddy figure, it helps me feel safe and loved. But over the last year or so, I've found myself wanting to take on more care-giving roles too. It's like we're both now trying out being a big sister/brother to each other, kind of switching back and forth between that and our traditional roles. The issue? We don't always agree on when it's time for little me to go to bed. My partner tends to be strict about it, he likes things to wind down before lights out so that we can both enjoy a good night's rest. But I've found myself pushing back more and more against those times, wanting to play longer even after my caregiver wants to end the day. It started with little disagreements, 'but daddy, just five more minutes!', but it's grown into bigger arguments. We love playing together as equals too much not to resolve this somehow. I want us both to feel satisfied and happy about our dynamic no matter who is in charge at any given moment. So here we are, stuck in a weird space where sometimes I'll comply and other times, I don't, it feels like I'm testing boundaries more than respecting them. And you know how frustrating that can be! We're both adults with decades of life experience between us, but these playful little power struggles...they take a lot out of us emotionally. I wonder if this is normal for couples who explore different role-playing scenarios together? Or am I just being difficult because I secretly want more control over when it's time to play? Thanks in advance for your thoughts and advice! It'd be great to hear from anyone who has dealt with similar issues or has insights about balancing these kinds of adult dynamics.
