Hi K.,
I am definately no vet in any of these issues.
My experience with my 2yr old - 25 months to be exact, has been relatively simple in some areas.
For instance, bedtime had never been an issue and we transitioned her to a toddler bed at 21 months. She screamed a few nights and then was fine, never got off the bed until 3 months later, when we took the paci.
Then it was a nightmare, we had to regress to putting the toddler side of the crib up against the wall to do this differently.
I have tried putting her on the potty and she freaks out and screams so I don't force her so it doesn't become a real resistance.
I think children mature at different times.
My MIL and her best friend "claim" their kids were potty trained at 9 months and 18 months. Dressed and undressed themselves, they claim.
However, as much as she brags of his independance (my BIL) and his early development, at 40, and having been with his brother nearly 10 years, I am yet to meet a friend, a girlfriend and he still comes to moms house and expects dinner - HIS WAY - 4 or 5 times a week lol.
So, I wouldn't put all my eggs in one basket, potty training them, beds whatever, it doesn't mean they will or won't bee well adjusted as adults, it all comes when it's time for them I suppose ;) I try to be easier on myself.....
Anyway... I'm rambling.
