Hello, I understand your struggle with potty training for poo poo. I am mother of two and went to same problem. I have one son and one dauther , both are school age now. The best advice I can give you is to back off some. When my daughther was 3 she had this period of regression and it seem like the more, I push her the worst it got. Just relax,and let her take her time, I know you said she will start pre school in August, Trust me not all the children will be totally potty trained. Just send x clothes or pull up. Usually when the toddler go to preschool and see other children beign independent this encourages them to do the same. After entering , pre-school within 2 months my daughter finally became fully potty trained. Toddler just struggle with poo- poo part.
Trust me on this , just relax and she will get, also do not let any one tell you she should be potty trained by now. Every child is different. Some just like to take their time.
Hope this helps
