Definitely a good baby, both on my own and with my previous caregivers. Being a good baby just comes naturally to me; I diaper up, throw my baby clothes on, drink a bottle, play with my toys and when I had caregivers, I would listen to what they had to say and we spent a lot of our time together just cuddling.
To be honest, I never understood the appeal of being a bad baby, if only because it sounds like too much work, both for the baby and for the caregiver. I feel like I would have to go out of my way to do naughty things that I wouldn't do otherwise and I don't know, that just seems forced and rude to me.
I can understand the desire to be naughty in some cases, say if the participants both viewed this as a strictly kinky thing (I view it as more of a part of who I am and a form of therapy) or if aspects of their AB/DL cross-pollinated with BDSM or dom and sub dynamics (I know you could make the argument that most AB's are submissive, you'd be correct, but that doesn't mean all of us thrive off of spankings and harsh discipline), but outside of those very specific instances, being a bad baby seems really inconsiderate. Why, I remember reading horror stories on Fetlife or in interviews with professional Mommies where they talk about AB's who were bad on purpose, AB's who drew on the walls of the nursery space or who deliberately messed themselves even though messy changes weren't a service the pro Mommy provided *
shudders*
I'll also say this, based on experience, I think most caregivers, unless they have a stern, disciplinarian dom side, much prefer watching after gentle, obedient babies.
Although, to each their own I guess. I suppose that if the naughtiness was benign like a small tantrum, or hiding from Mommy when she wants to change you, or splashing around a bit too much in the bath, or refusing to put away your toys and if there was a structured or planned element to it, then being a naughty baby could be fun, but for me, it's just nothing that has ever blipped on my radar and it's still likely something I will never be interested in.
Good Baby all the way

In answer to the final question, having both regressed on my own and with past partners, there are definitely perks to both, but yes, having a caregiver, even temporarily, is better than having none at all. Once again though, don't rule out solo regression time, that's fun too
