What exhausts you more as a parent: mental drain or physical fatigue?

Me and my partner are hard working parents of two little girls. I work as a preschool teacher for 24 students and he works as a machine operator.

One night I told him if he could put the girls to sleep since I was exhausted especially since we did enrollment that day. He told me he was tired and sleepy. Eventually it led to us arguing about who is more tired. He thought since I “watch” kids it’s nothing much. I’m just curious as to what everyone thinks lol
