Hi sounds frustrating! I have 3 children and my first 2 were very different. My son finally started going potty on his 3rd birthday party but everytime we put a pull up or even underwear we were running into the same things as if he were in diapers. So we let him go completely w/o underwear and eventually once he didn't have the feeling like it was his diaper or pull-ups or underwear he did it. Also when I was potty training my daughter we pretty much had to do the same thing! But when they are ready they will do it too. Hope this helps!
