You have millions of years worth of instinct and two very awesome sources of great comfort and food. Dads just dont have that.
I think it's awesome that he wants to try to comfort. I usually see the opposite. I would share the "S"'s with him when she calm and happy, but also make sure he understands that the main source of food and comfort naturally lie with you. It' not because he didnt read any baby books.
Id imagine he's probably more frustrated than you are. He probably feels like he's unable to make his daughter happy. I would be very sensitive to that. I would say "She's not mad, she's hungry." That takes it off him, and on to a very basic fact that she just needs food.
