Help! Unhappy baby 😭

Jess

My baby girl will be one month on Tuesday. For the last 2 days if shes awake and she’s not eating she’s crying. She used to be able to just chill awake and allow us all to talk to her and hold her but now everyone is getting so frustrated bc all she does is cry 😢 She’s been on gas drops and gripe water but still doesn’t seem happy/comfortable. Any advice???????
