I'm not sure what your setup is like but here is how I dealt with a similar situation. I have a 3 year old who does not sleep, although parents want him to. My playroom is separated from the kitchen by a gate. He must sit/lie on his mat and have quiet time alone. He is allowed books but no toys. I sit in the kitchen, have lunch, read etc. I can see him but there is no contact!!! Works perfectly and he often falls asleep anyway!
