she is nearly 16 months and has started saying "poo poo" and then 30 seconds later she does the "poo poo" face. She has also started taking an interest in the downstairs loo. DP thinks we should get a potty and introduce her too it after her bath. She always poos after a bath (usually on the floor). I know she is no where near old enough to be "trained" but is introducing a potty a good idea at this early stage ?
