First, as I'm sure most moms on here will tell you, night training is developmental and there isn't much you can do to speed it along. Just be patient.
Second, if your daughter is ready I think as long as you pick a method and stick with it she will be fine. I personally think pull ups are a waste of money and just confuse kids because they are basically diapers. We did a 3 day method with my son when he was 20 months old, he caught on right away and we never looked back. Whatever you pick you just have to be consistent and realize that she's only 2 so she will not be perfect (just like she didn't walk perfectly the first time she tried). It takes some time and a lot of patience. I think the keys are being positive through the whole process, even the accidents, and being consistent. You can PM me if you want more details about what I did, but you can also just google and find many books and websites on 3-day methods.
