Part 2- Teaching my 14 month old to sleep....?

Thank you so much for the insight, inspiration and direction to help get my 14 month old on track to fall asleep by herself and eventually to sleep through the night in her crib. The first day I was determined to start the new regimen, Z took a long morning nap and inevitably did not nap in the afternoon. As it turned out, she was pretty sleepy so we gave her dinner a little early and following our regular routine got her in her crib and hour early. I barely had to hold my ground because Z was so tired she fell sleep in about 10 minutes. The next day I purposely pushed her am nap an hour later, she slept longer and wahlah- same as the night before. OK- now today, later nap, but only for an hour and no afternoon nap. By 5:00 she was beyond exhausted. We had a super early dinner, bath, etc and she was out by 6:50... Am I pushing her? I look for signs of Z wanting her second nap and although she seems sleepy and we have quiet time it has not resulted in a nap. Just looking for insight.
