Yup, agree with playfelt. He may be a super-emotional child, who just needs to work through this. Don't give too much attention other than using a positive voice to talk him through. If you're going over the gate to go to the washroom, just say in a kindly but matter-of-fact voice "I will be back in a minute, (name). You're okay."
I would guess that this, too, will pass. He seems to enjoy coming to your place, if he's reaching for you in the morning!
