My two and a half year old has started with-holding poo (we haven't started potty training yet). It has been over the past week and a half, and she has been pooing about every three to four days, she is with-holding it until she can't any longer, therefore the poo she is doing is bigger and harder and causing her pain.
She has plenty of fruit and liquid in her diet, and is getting the urge regularly, just withholding it.
Any advice on what to do?
