My ds is 20 months, she knows when she's pooed because she'll hold her nose say 'yuk' and go lay down on the settee (this is where we change her) .
Lately for the past week or so she's been pulling at her nappy at the front saying 'yuk' and laying down on the settee. But theres no poo there.
She dosen't pull her nappy down at the front when she's pooed, so I think she knows when she's weeing.
I think she is a little young though. What do you think?
