12 days old and grizzly and clingy

Charli
Hi my baby is 12 days old and today she has been super clingy and really grizzly. We can't find anything wrong she's eating and soiling nappies, bringing up wind fairly easily. She just won't be away from me or hubby and is really grizzly when trying to get her down..... what could be going on? I feel like I'm missing something :(
