Hello, thankyou for approaching DoctorSpring, Potty training is a sensitive issue with children. From the symptoms you have mentioned above, I would say stop the laxative. Your daughter is having an urge to defecate and the increased frequency has probably made her anal region sore. Kindly examine her anal region for any redness? But do this very reassuringly as it will already be upsetting her.
Let me know if there is redness so I can advice you accordingly.
You can reply as a follow up question.
Thankyou
