Went the way of the dodo with the new board but having read it a zillion times I think it went like this...
lo stopped nappping and then starting sleeping less and less at night until was only sleeping 8-5. Mum watched for tired signs put ds to bed at 3:30 and he slept for 2 hours, went back down to sleep at 8 and slept thourgh to 7. they pushed the nap back to 2:30. The schedule also used to be part of "what does your toddler's day look like?" but it looks like its been bumped from there as well.
