Breastfeeding vs poop

My baby is 11 days old and I breastfeed and pump no formula . Lately her poop has been more runny I would even say liquidity...

She’s seems more fussy too 🥺 I feel her poops and gas makes her real uncomfortable

I researched the vitamin K drops my peds doc gave us and ask other mamas and they said it made their baby’s fussy gassy etc . Anyways so I stopped that 2 days ago to see if I see changes . I will replace that .

But what do you guys think ? How can I help her ? I really don’t consume dairy either . Or hadn’t for like a week
