go to the bathroom on their own? DS (28 months) has been trained in the last month and regularly goes to the bathroom both on his own toilet and the big toilet (prefers it for #2). But, still needs our assistance most of the time.

If we are bottomless at home he goes himself on his toilet. He tries to with pants/underwear too, but can't get them off all the way just yet on his own.

How old was your LO when they started going on their own?
