Phases during potty training

[Frenchy]

My son is 2 yo, and since the last 3 months, he is used to go to the potty during the day, when we are home. The easiest way now is that I leave him without any knickers or diaper, and he will go by himself to the potty, without asking.
It's ok as long as there is nobody home, but when we have visitors or workers, it's not so nice to leave him showing his bumps to everyone ;)... so I put knickers, but he thinks it's diapers and will pee without even going to the potty.
I think it's still a bit too early to go out without diaper... how do you go through the different phases ? do you just keep on trying and trying till he gets it ? or should I wait until he is a bit older (I think he wouldn't know how to put the knickers down right now...).
Thanks for any good tip !!

i would say to try putting underwear on during the day when you are at home by yourselves.

personally, i've never toilet trained without underwear as i figured it would mean i'd have to do it twice, just like what you are experiencing.

underwear is a must
