Oh dear, I thought it was pretty normal too? My 3.5yr old DD is completely toilet trained for peeing but still asks for a nappy and then tells me she is going to hide to poo. I just let her do her own thing... When she's ready, she'll poo in the toilet. She wears knickers to daycare and waits till she's home for a poo.. I think she has great bladder and bowel control
