Well, I had two totally different experiences with my son and daughter but both potty trained almost immediately when they were ready. My dd would probably have trained with consistency at about 18 months but she was in daycare and they did not have the facilities to help with that until the 2 yr old room so we didn't try that early. At about 26 months, she told me she wanted big girl panties like a friend had. I told her that that meant she had to use the big potty. She said fine and we went on a Friday and let her pick out panties. ( She was a very verbal kid.) The first day she wore her panties we stayed home and she went about every 15-20 mins and sat on the big potty. No accidents but we put the pull ups on that night. Next day same idea but she went every 30 mins - an hour with no accidents. She even played outside fully clothed and came in to potty. After that she had no day or night accidents and we no longer used pull-ups. If we went out, we went to the bathroom first at every store. We new where to go at every restraunt and department store but she did great and became very independent quickly. I don't think it would have been so easy at 18 months, although she would have gotten it eventually.
Now my son....oh boy. He resisted potty training with all of his might. I really think it became a rebellion for him. I say this because we tried everything....all the teachers in the 2 yr room tried their best, too. He was stubborn. He didn't even mind at 2 years 50 weeks running and playing in the yard with soaked big boy underwear on. Just didn't care. However, when I finally decided to just tell him straight out that he would be held back with the 2 year olds ( the babies to him) if he did not get this, he was trained over night. He "decided" right before his 3rd birthday to be potty trained completely. I'm not sure if we went wrong somewhere or if it was strictly a battle of wills from the start but he potty trained when he wanted and it was a complete deal.
I would say if your daughter takes interest in it and shows progress, go with it. If she doesn't seem interested or you get stressed, just wait a little while and introduce it again.
