HANGRY baby

J
My LO had been eating like a champ, 10-15 mins each breast and would comfort suckle until he fell asleep. He just turned 6 weeks and The last couple days he has been eating 8 mins max on one breast and getting extremely frustrated not falling asleep like he used to and not eating as much (or as long) as he used to. I usually am lucky to get him to latch again to either boob but most the time he just starts screaming. I know there's plenty of milk in them so I don't know why he is getting so frustrated and not staying on. It seems to be our two midday feedings, he's typically his normal self otherwise. Any tips or advice or insight?
