I have raised 4 sons & can honestly say that the nights that they had sleep issues were when nap time was altered. My own almost 4 year old is the first to sleep and 2 1/2 hours later the last to wake @ nap time ...and sleeps a full night with no issues (8pm to 6am). I honestly believe that most sleep issues are a result of routines out of whack...as it sounds in this case. I do not wake my children (daycare children) before the 2 hour mark (& only then to fit in our snack/diapering routine/home time routine. My opinion is that if they are sleeping, they need it. As to what to say to Mom...she is grumpy, this disrupts my daycare routine, falls asleep immediately, my daycare policy is a mandatory rest period of .... hours...how can you control if she closes her eyes at all? Perhaps a bigger centre would be a better choice for her with staffing to allow for non-nappers?
