My baby girl is 16 days old, she's breastfed, and the last day or two she's been so fussy her face goes red and she cries trying to push gas/poop out. (Her poops look normal though) I feel terrible that she's in so much pain! I've been trying to look up some solutions and I'm wondering what has worked for you?

I have gripe water but I'm hesitant to try it because of how young she is. She was born at 37 weeks so could it just be her digestive system still needs to mature a bit and she'll grow out of it? Or food intolerance with something I'm eating? Please share your experiences, TIA!
