Normal behaviour?

C 🖤

Is my LO the only one who gets a bit crazy when he's nursing? He latches on straight away but will then pull away and move his head around really fast with his mouth open, looking for my nipple, then head butts my boob and starts nursing again. He does his a few times during each feed. He'll randomly flail his arm around and frantically try to grab at anything he can with his hand, which sometimes ends with him grabbing my nipple and crying when his mouth can't get to it because his hand is in the way.. 🙄 He also kicks his legs around and makes groaning noises while nursing. Is this normal? He's always done it so I assumed it was just a quirky little thing babies did when feeding but a friend just commented on how funny it is and said she's never seen a baby so active while breastfeeding.
