it is a VERY traumatic time for the child - a lot easier for you. But do not worry - it will work out. You have to be understanding and sympathetic. If she does not want the potty then that is OK. Just say that OK well if she needs it later it is there. Success with my 3 year old son was letting him run around the back yard, naked on a hot cloudy day. He came to me and said he wanted to do a pee. I said OK - here is the potty. He sat on it and said "I can't go". I said OK don't worry - wait til later. 10 mins later he sat on the potty. He peed near a pint. So it is happening. It works faster if you leave the diaper off. The diaper ends up as a sgnal to pee and poo. His mother does it through bribery (not a good idea IMO) - I do it through communication and a relaxed attitude.
Problem is as I see it is that too many parents are too bossy. Do you like it if you are bossed around? You do not need to answer - I know the answer
