DD1 is 2.4 and although I haven't started potty training properly with her yet, she does like sitting on the toilet. She takes off her nappy and climbs up, if the training seat wasn't there, she would sit on the toilet seat, but won't use a potty. She has done wees on the toilet like this.
However, when she has, the stream has gone somewhat upwards, over the raised lip of the training seat and onto her foot and the floor.
I don't know if this is at all common, but I have no idea how to help her get her "aim" right, it's not like with a boy who has something to point. I don't think I could do it myself if I tried!
Does anyone have any experience with this and any suggestions?
