You could also try getting your smell into his blankets. Just carry it around with you and put it down with him when it is nap time. He may think that you are still there with him. You could put one of your jumpers or tops etc in there with him instead. I know what you mean about it being draining. Hope it settles down for you soon. Make the most of your cuddles. I rarely get them now unless he is completely zonked or I am feeding him!!! There are just way too many other things to see and do!
