Do you still have any of the sedative you used when you transported them, or was that a single dose? If you have some left maybe you could give Wilbur a little, just enough to help him sleep so you can get some sleep as well.
Would it work to have Wilbur on the bed with you while the kittens are nursing? Just keep him on one side of you and the kittens on the other side so he isn't in direct contact with them.
