How long should my kiddo wear pull-ups?


My daughter is doing great keeping her pull ups dry all day most days. She still wets them during nap time (and often poops too). I still do prompting but she also self initiates. Is there a draw back to keeping her in pull-ups versus switching to underwear soon? It’s been going so well - I don’t want her to get stuck here and regress but I know underwear has more mess potential and juggling with naps and poop. Any advice?
