As Little Andrea has said, many AB's find their baby time or little time to be therapeutic, I'm in that boat myself. Honestly, nothing chills me out and helps me forget about the hustle and bustle and the frustrations of adult life more than simply throwing on a diaper and a onesie and regressing. In fact, I think when many AB's and Littles encounter stress or resistance in their adult world, their desire to regress spikes. So, yeah, one can explore their AB/DL and Little side as a means of therapy. I often say that my baby side is both a part of myself and a form of therapy.
As far as advice and tips on being an AB/DL or how to be an AB/DL, I'm not sure anyone has the answer. All ABs, DLs and Littles are different from one another and these sides of ourselves can be quite diverse and varied. The best way to figure out where you lie as an AB/DL is to simply explore.
I have some broad-stroke tips that could help guide you through regression and discovering some of the ins and outs of your AB side, for instance, try writing a list about what activities appeal to you within the AB/DL realm, also, do some self-reflection and try to think about hobbies, shows and items you enjoyed when you were an actual child. Taking stock of such things can give you a rough idea of how to begin exploring this side of you, it can give you ideas for things to try, items to buy, etc. At the end of the day though, everyone is going to be a little different, so there are really no good answers on this front I'm afraid. When you have the time, simply explore some of your AB/DL desires, the more you practice and the more comfortable you become with them, the more you will begin to understand what being an AB/DL means to you
As far as hiding places, I find having a bin in the closet works, I know some AB's go even farther and I've heard of some having locked safes. When I lived with my Mother, my hiding place was a large dresser, if you removed the drawers from it, there was a ton of space between the base of the dresser and where the drawers sat, enough for a small box of baby items and diapers when removed from the package. If you live on your own, however, there really isn't any reason to hide all your AB items, unless company is coming over. Right now, my diapers line my closet shelf and my baby clothes are folded neatly away in a rubbermaid bin inside my closet and sometimes they're even hanging right up alongside my big boy clothes
As far as the Sissy question is concerned, I wouldn't know much about that, I'm a baby boy through and through, but there is a Sissy section on this very site and I'm sure some of the members there can better advise you on that.
I wish you luck with whatever it is you're dealing with as it sounds as though you have a full plate at present. I'll also say, there's no need to rush things if the opportunity isn't there. When the time and space reveals itself, take stock of what behaviours and objects appeal to your AB side and simply explore... also, be sure to have fun when you do
Good luck to you
