Daughter's pull-up stays dry but her pajamas don't during the night. Any advice?

Hi all,My five-year-old daughter still wears diapers (pull-ups) during the night. They have been consistently dry for the past month and mostly dry since the summer began. However, we still have her wear them because if she is not wearing a pull-up, she can only go a couple of days without wetting the bed during the night. I don't really understand why this is happening. Has anyone experienced anything similar? Any advice? Thanks! via /r/Parenting https://ift.tt/2U6LOa8
