I have recently come across this issue as well. I now call my nap time a "quiet time". Each of my children have their own space to sleep and my 3 year old who the parents don't want to sleep, is in her own room laying down, but with tree house on very quietly. This way, the tv is on so that it can occupy her if she is awake, but not to loud for the other children. However if she needs a nap she also tends to doze. I have discussed this with my daycare parents, and they are ok with this policy/comprimise. The only time there is any difference is when it is a PA day and I have my older children home, then they get to play on the computer quietly...the keyword being quietly. 12:45pm until 2:45pm at my home is QUIET time, no if's, and's or but's.
