M.G.
If I understand correctly, she may be a bit impatient. Try reading some books while she potties and give her some time to go poop and something she enjoys while doing it! She, like my son, is probley anxious to get back to playing and wants to speed up the potty process. We sometimes read 6 books at one sitting to finish business and sometimes he goes poop and 5 minutes later has to go again because he didnt finish because he was too anxious to go play! Good Luck
