Longest my son wears one is his overnight one which is between 10-12h normally depending how long he is asleep. They are pretty easy to use but you may have to experiment and find what style works best for you (Covers, Pocket’s, All-in-Ones). Personally I really like the ease of pockets but when I first started doing research I thoughts I would love covers.

I don’t have any issues on car rides but I didn’t cloth diaper until my son was 6m and he doesn’t have all too frequent bowler movements but they are way better at containing blowouts than disposables imo. :)

As for if they are worth it.. suppose it depends on why you are doing cloth and hopin to get from them. I like them because I never have to buy new diapers and never worry about really running out. They also save money especially if you have multiple kids. They are obviously a bit more work than a disposable diaper but easy enough to deal with once you get your wash routine figured out. Feel free to message me if you want to talk more though!
