Hi L.. I too think that 18 months might be a bit too soon. My daughter (now 26 months) was interested aroud 18-19 months and was going potty all the time at home and wearing cute panties and then she totally regressed so i completely let it go. About a month ago she started asking again to go potty. She loves trains so I drew a big train on a big piece of posterboard and everytime she goes potty she gets a sticker. SHE LOVES THE STICKERS! Then when she had 20 stickers we took her to chuck e cheese and totally made a big deal about how we were there because kate went peepee on the potty like a big girl....she loved it!
Also, I am having a hard time getting her to poop on the potty so now whenever she has to poop I know its coming because she gets really ansy and brings me a diaper. when she fills the diaper, i let her watch me dump the poop into the toilet and i tell her this is where we go poop. i think she is starting to get it a bit more.
i know that you are anxious to get her out of the diapers, but just be patient...she will let you know when she is ready. good luck!!
