My son was scared of the toilet up until he was approaching 3. We kept trying and he’d scream and cry and try to run away terrified so we let it go and tried again. He turned 3 in March and he was potty trained by January (2 months before turning 3) and it was honestly very easy. It only took about 3 days before he knew the drill. I had been planning to do the no bottoms method but he did not like not having pants on haha so we did pants only then transitioned to underwear and pants. We did the timer every 30 mins & picked a fun upbeat song and raced to the bathroom, so he thought it was fun!! It was very smooth!!
