My milk doesn’t seem fatty enough!?

Madison

My milk is pretty watery it seems like, it’s a light white color and typically thin in consistency. My maybe is 7 weeks and still eats every hour expect at night and sometimes we don’t even make it to an hour! I know he’s getting enough milk but I’m starting to think it’s not fatty enough and that’s why he eats so often?!

How can I produce better milk, is it my diet?!
