If leaving him overnight, put down a puppy pad or newspaper.
I split the crate into two halves, bed in one half, puppy pad on other half.
Oh and don't forget a little bowl of water as the back of the crate. I made the mistake of putting it at the front and wondered why water went everywhere!
I also put a few bits of kibble food in, probably because I'm a fussy mother
Although I always put a couple of toys in each night and rotated them, I can't honestly say they were used much.
I did try getting up one night to take Millie to the toilet, once was enough !! She was very unsettled after that. Millie was quiet all night if left alone, pooped in the corner for a few weeks.
Enjoy your first night, the greeting in the morning is second to none
