Hi S., I didn't read all of the responses so my apologies if I'm repeating anything...I think every child is different and they do things at their own pace. That said, my daughter is 2 and 4 mo. and is almost completely trained...I don't say that as comparison, just to say I think your training is totally age appropriate at this point.
some things that worked well for us:
1. She LOVES the Elmo potty DVD- I would highly recommend it- she asks for it every day...and loves it better than any other Elmo DVD's we have...go figure!!
2. We have done incentive programs...when we first started I put a trree on the bathroom wall (that I made out of construction paper- very simply) and every time she peed she put an apple sticker on the tree and we did a potty dance...she was so excited (the first few days we did this I made it fun in the morning- we drank LOTS of fluids- special juice, etc. to make her pee a lot!).
3. Once she started getting the hang of it- we moved from stickers to fruit chews-- I would give her one or two every time she went-- I kept them in a container on the bathroom counter- she also liked m&m's...actually the m&m's really got her going a lot and I switched to the fruit chews b/c they felt a little bit healthier (probably not much though!!)
now we're working on the poop which is a while other story- but besides that she is out of diapers all day...
good luck!!
