Willow: yes, I think you are right about 40 mins perhaps not being such a big deal at her age...(although it stops me from getting anything done!). She has occassionally forgone the morning sleep and has done a long 2hr+ sleep, so maybe she is heading towards a one big (hopefully) day sleep.

When she wakes up she is not at all grizzly or upset, maybe 40mins is all she needs at this stage.
