Potty training is very frustrating. I my daughter will be 3 in september and my sons are 16 months and 5 months. My daughter is obsessed with money. She loves it and when I first started working with her, my brother told her go potty and I will give you money. She took all of our change, but it took up 2 weeks to have her out of diapers/pull ups and into panties. That is how he is potty training his daugher now and going pretty well. She would get a dollar bill when she had a bm, otherwise just one coin if we asked her and 2 if she told us. She was completely pottied trained by 19 months. She has now surprised up and potty trained herself at night, we dont even put a pull up on her at night. Some people may think its crazy, but we didnt leave her potty chair in the bathroom, it was in the living room because I didnt want her to feel like she had leave everything to go potty and that she wasnt in troble. Try to make it fun for her, give her a reward she really likes. Soon I will be working with my middle child on this and he has taking a liking to money so we will give it a shot with him. Good luck!!!
