With my 2 yr old i had the same issue. Everytime i had to go to the bathroom i would announce it to her and go. I got her dad to praise me after i went, He would say way to go Mommy you went potty on the big potty. It wasn't long and then she wanted to get that same praise. She would say i have to go potty and run off to the bathroom. It probably ould also help if you get his dad to sit instead of stand. My daughter was confused by why her dad was standing and told him he needed to sit dow
