10 week old ALWAYS hungry

I’m so freaking tired 😓. My boy is 10w4d old. He literally won’t stop eating. I know I have plenty of milk because it’s always dribbling down his cheek, and even sprays sometimes. But this boy will not let up. He will only sleep if he is on my boob, and the second I take him off he is crying for more. He’s been on my boob for four hours now and I’m so tired 😭😭 what is happening ?!
