I also have small hands, and I used bridge cards for about two years before I felt comfortable enough with the basics to force myself to use poker size. I own a lot of bridge decks, but I rarely if ever use them anymore. I never carry them with me. Sometimes I play with them a bit and especially for new or especially hard moves they can make it easier and less frustrating to learn with. However, the size of your hands (opposed to other parts of your body) really doesn't matter. Mine are small, but larger compared to Jay Sankey, and he obviously has no problem with poker size. For a long time I thought I could never palm with my hands, and now I do it all the time with no trouble at all.
So, keep using the bridge decks if that helps you learn, change them often and once you have a move down pat, try it with poker size. As you get experience, you'll be much lighter on your handling and the cards will behave as new for much longer. I remember going through two or three decks a week, sometimes two a day, especialy as I concentrated on false shuffles and deals. I never use fanning powder as I can't get used to the feel of it. Now a deck can last for months.
Sooner or later you'll switch to poker size, which are cheaper, easier to find, and more consitent with special cards such as double backs or faces, or packet tricks. you'll be happier in the long run if you switch to 808's, but the bridge size will help relieve frustration which helps you practice more.
Some moves are much easier to cover with the larger 808's. I still can be 100% reliable with a 3 or four card pushoff with bridge, but with poker size, I have to steal a glance for anything more than two. My passes are much better with 808's, but faster with bridge. second deals and double lifts look better with poker size. If I borrow a deck and it happens to be bridge size, I secretly am happy with it.
