Please does anyone have any advice how I can get DD 3.9 (ASD) to have a wee or poo on the toilet. She knows the routine, can pull her trousers and pants down, attempts to flush the loo can pull her clothes up and wash her hands. She can tell me AFTER she has done something in her pants. What she does not seem to be able to do is anything on the toilet she will just not wee or poo down the loo. She manages to stay dry at nursery most days for 3 hours so she must have some control - any ideas???
