Hi my dd who is 2.4 yrs old is now potty trained (wee). im really proud of her as it only took a couple of days and shes had very few accidents. shes nearly dry over night (fingers crossed as 7 yr old dd has nocturnal enurisis). but when it comes to doing a poo she gets very upset no matter what i do.she walks up and down shouting that she needs a poo (i can only describe the walking up and down as being like a woman in labour iykwim) she wont sit on the potty or toilet, doesnt want a nappy on and normally ends up pooing in her knickers. she gets very upset and doesnt want me to change her. im not sure what to do about it, i reasure her that its ok and try to gently persuade her to go on the potty to no avail. any ideas?
