DD is 3 years old and has been potty trained since the summer. She took to it fairly well but has gotten worse in recent months at poo. She will hide herself away and will soil herself in secret or will deny that she needs to go and will fight if we sit her on the potty or toilet. She prefers to soil herself and will do this 2/3 times a day either at home or nursery.
When I ask her about where the poo needs to go, she will say 'the potty' or 'toilet' and doesn't seem bothered by having soiled herself, if i don't notice she will just walk around with it. If i ask her why she has done it she speaks gobbledegook or she will look away from me and will avoid eye contact or will change the subject.
She's not easily motivated with toys or bribery, she just doesn't care. She will be bribed with biscuits but this isn't good for her. She's not fussed with stickers or toys or toys being taken away.
Im really stuck as to what to do!
