Constantly Fussy Baby-Possibly Formula? 🍼

My daughter is 4 weeks old. She started out on breast milk and Similac Pro-Advance and she has been fussy so I’ve switched her to Pro-Sensitive (like I had to do with my son when he was a newborn). No more breast milk so it’s strictly formula.

She’s constantly fussy. There are hardly times where she’s content and quiet when all of her needs have been met. The only other thing I can think of is formula. She’s so gassy all the time. She has no issues pooping, though.

I’m going to talk to her pediatrician on Monday at her appointment, but what formula would y’all recommend if she’s already on Similac Pro-Sensitive?

Thanks!
