Potty training

Brandi • Married to bff || 2 boys & 1 girl

My daughter will be 3 next month and she still isn't potty trained. I've tried everything I can think of to encourage her. I've tried letting her go around naked or in panties, putting her on the potty every 15 minutes, and letting her know she can have a sticker if she goes. All of this to no avail. I'm all ears to any advice!!!!
