Agreed, if the rest of her naps are 1.5 and I'm her own then I would do what you can to get her to take that cat nap ( letting her sleep on you, a little rocking etc.) she is still very young and when my little guy was that age I would do what I could to get the sleep for him but tried to stick to the easy and somewhat limited the props. I would shorted the activity time in the evening too. Keep in mind the easy routine is just a guide. There were many night where I would spend countless times going in and out of the room to settle him almost 2 hrs sometimes! I use to look at the walls sometimes and wish I had a tv in there so it wouldn't be that bad lol! Good luck!
