Sleep issues

My 2.5 year old daughter usually has been very good about going down to bed. If she didn't go straight to sleep she would lay quietly until she fell to sleep. I would maybe in a blue moon have to lay her back down. But lately she has been really bad. I've had to lay her back down at least once every night.. sometimes 5 times and once I just let her fuss herself to sleep. But lately since we've been working on potty training she uses that she has to pee or poop multiple times. She's in a pull up just in case. My issue is I want to support her telling us that she needs to go.. but when she has been in the potty 3 times and done nothing but still says she needs to go 5 minutes after you leave.. what do you do? This has gotten ridiculous!
