So - I have heard two people recently mention these.

Looking for reviews and or experience/advice on them.

DD is 2 now...we are moving her to her Big Girl room and a toddler bed in October. I am thinking this may be a good tool to utilize in the transition. She sleeps well now (7pm-between 6 and 7am) but has just recently started in the morning (and unfortunately sometimes overnight) stirring and saying "all done night night"...so I think she is maybe at a point where she could understand the concept?

TIA!
