You don't have a choice,
But perhaps he needs a home enviornment instead, Daycare might be just too much of a change,
Try a family home daycare, as its much more relaxed and less regiment.
Its a difficult transition for him, to go from Gpa who lets him relax and play at will, and then to be told what to do every second of the day with no recourse.
