"Actually, I don't need to go right now"

Potty training was going really well, but lately she has regressed. Apparently she is just having too much fun to go potty. She will tell us that she needs to go and then as soon as we start to walk away from whatever she was doing she will give us the "Actually, I don't need to go right now". As you can guess this leads to her going back to playing and then waiting too long to make it to the potty in time. We are also still having the pooping on the potty issue which I have no idea how to remedy. Sometimes I wish we could just fast forward through these unpleasant parts of childhood.
