For those starting potty training, are your little ones still in cots or are they moving to beds?

I really wanted to stick with a cot as long as we could (like 3ish if we could get away with it) but now my daughter is showing a lot of willing and already starting to potty train with little encouragement I’m second guessing if we should transition her to a bed ready for night potty training.

I don’t want to put too much on at once though either so not sure what to do for the best 🤔
