Twirl - I can't advise you on if it's too early as my ds has just turned 3 so I can have a proper conversation about it with him.
I just wanted to tell you that it's quite normal for accidents at the start, even my ds would just stand there and let me know he was wet after.
I'm a childminder and look after several other children so potty/toilet training went downhill during the week - lack of concentration. Since it's been just the family again, he's been MUCH better.
Here is my daily record since starting last Saturday (just to reassure you):

If she's showing signs of being ready then I would keep at it as they seem to just 'click' when they are ready. She does seem young still so don't be too upset if she's not quite ready!
Best of luck :)
