Toilet training advice?

My daughter was 16 months and she basically potty trained her self. After she started using the big girl potty she wanted nothing to do with diapers even at nap time or at night she would not let up put them on her. she is 9 years old now and has never had an accident (AMEN) I would just say be grateful for her wanting to use the potty at such a young age and just encourage the pee on the potty the more you try to make her she will become discouraged and could regress with the potty thing. Just let her do her thing when shes ready.
