Potty training.

My son is 3 and we are working on potty training have been for about a month now I’m not pushing him to go but I ask him a few times a day if he needs to go to the bathroom and he will say yes or no if he does but does anyone else’s little one thinks they needs to be naked in order to go pee, every time I have to take his pants shirt and even his socks off other wise he won’t stand in front of the toilet, we were at Walmart and I had to go pee so I went into he family bathroom with a big and little toilet and he wanted to go pee but he thought I was going to strip him down right there and I told him no I can’t and he started to cry bloody murder just because I wouldn’t.
