Potty Training 101. What am I missing?

My daughter just turned 2 & is showing all kinds of signs of being ready to potty train. Tonight she was grabbing her diaper, squishing her knees together & said “mommy I pee pee” so I just rushed her to the toilet. By the time I got her diaper undone though it was too late & she had already peed in the diaper. But I held her over the toilet for a little while after that & let her ask questions. Showed her how to wipe with toilet paper & let her flush the toilet. She seemed super excited.

So it looks like we’re diving into this potty training thing!

This is my cart so far but I just want to make sure I’m not missing anything vital that would be a big help

Am I missing anything that I would need or that would be super helpful to have??

Also any tips or tricks would be greatly appreciated!!
