There are a couple in my area that offer the service. What you would have to find out is what is required in terms of supervision. If an adult must be awake while the children are in care then you might want to revamp the service to just offering evening/overnight care and then using the daytime hours for sleeping yourself. I would mean working 2 of the three shifts either doing day and evening or evening and overnight or overnight and day which I think would be the hardest. If you are going to go to the trouble of offering the additional service might as well make it for the hours that most don't do which would be the evening and overnight shifts. Without help not sure you could do the full 24 hours unless you are allowed to sleep.
