My 20 mth old was completely potty trained for about a month up until 2 days ago. She has been having a ton of accidents it's so strange.. She's been peeing frequently where before she could hold it forever! I'm wondering if she could have a uti? She doesn't have a fever though could she have an infection with no fever? She also doesn't seem uncomfortable so maybe it's just a regression... Anyone have any thoughts or advice?
