2 year old ready to potty train 🥹

So today I got up from bed and told my 2 year old I had to go pee once I got up she got up and grabbed her potty and dragged it in to the bathroom. While I peed she did too. I was so happy and jumped up and down clapping saying yayyy good job!!! Then we lay down after 15 mins or so she jumps up stands by the bathroom and says mama mama and I got up and sat her on the toilet and she used it again. 🥹🥹 She’s never did this before so I think she’s ready to use the potty. Yesterday I did notice though she would actually tell me when to change her diaper. Then today throughout the day she would run to the hallway and say mama mama and point to the bathroom and she would use it. She had a few accidents in her diaper/underwear but more in the potty. My baby is getting big and I think she is ready. She caught on so quick and also so quick to know to tell me she has to pee. 🥹 So my question is what’s the best type of pull-ups for a toddler also will be using at night so would be best if it works for extremely heavy wetters. Also when a toddler potty trains how does it work at night do they wake up or do they just pee since they’re still learning?
