E.P.
Just start introducing her to the toilet. My children used a child's toilet seat that was secured on top of the existing toilet seat. I never wanted to clean more toilets than I had to-and they actually liked going on it. For some kids, I understand that the "big toilet" can be intimidating. Just watch for the signs and adapt to a smaller one, if necessary.
After all meals, all beverages, in the morning, before bedtime, etc... just encourage her to try. Rewards are good (one - m&m or sticker for trying; two for actually going!) Make going potty fun! Make a fuss - whoop and holler when she goes! Read a book to her on the potty (sometimes she will say she doesn't have to go - just let her sit for a few minutes or even run water), play guitar or music, sing a song or make up a funny song when she actually goes. However, be sensitive to the fact that your daughter's needs may change and she may want to be in the bathroom, alone (my "ah-ha" moment was when my daughter was 2 1/2 and decided to do it herself! She didn't want me in the bathroom.) She may be on a path that seems like she "gets it" and then, has a set-back. Just keep the experience positive and understand sometimes, when they are young, they really aren't mature enough to "make the connection" immediately. That doesn't mean that you shouldn't try to be consistent in introducing her to the toilet. Doesn't matter if you work, full-time. Once you see that she has made great progress, you will get others involved in the process. Don't worry about her "success" - just start introducing her and take it from there. Don't overanalyze it. She will have set-backs and it won't have anything to do with the training that you have given her.
Good luck to you.
