3 year old keeps weeing her pants

My 3 year old potty trained herself 6 months ago and has been doing brilliantly, untill a few weeks ago! She is now weeing her pants more than she is actually going to the toliet. I have tried to talk to her about it and she is saying the reason she is weeing her pants is because she has some more. I have noticed that she does hold it in untill last minute, especially when she is watching her favourite tv program or playing her favourite game! How do i make her go to the toliet.....? The most frustrating thing is that she potty trained herself and its now like she cant be bothered. What do i do?

The way you can think of this is that your daughter has not completely mastered toilet training, though she is well on her way. Have her use the bathroom at intervals and establish a reward system for 'dry days'.
