In the last few days I've had some problems feeding DS (6 weeks), not at every feed but about half of them. He kicks his arms and legs and doesn't seem to settle for the feed. Then he falls off and screams in frustration. I've tried swaddling but he hates it and wriggles until he's free. I burp him regularly, he normally does burp. I've given a couple of different positions a go but can feel straight away that the latch isn't right.
Can anyone help?
