Overfed newborn help!?

Not sure where to post... But i am so stressed and tired my baby was born on the 1st of November and I fed him what I normally would (just like in hospital which he did so good) btw he is bottle fed and at that point he's normally full but i gave him a tiny bit more because he burped super good and still ended up trying to eat his hands and I was told by nurses while I was there if he's ever still acting hungry to give him a little more if needed so I did he burped again after that and ever since has been fussy but STILL trying to eat and there's no possible way he can still be hungry and he doesn't want his binky. I've tried rocking him, soothing him, swaddling him, I've been sitting up with him since 1:30am which is when he started eating and it's now 3:43am I've also tried burping him again he's spit up a couple times which is how I know hes overfed but I'm trying to figure out why he's still "rooting" as if he would want another bottle... I'm so lost 😥
