Probiotics and gas

Has anyone here had any luck with giving your baby probiotics to help with gas? And/or taking probiotics yourself if you're breastfeeding? And if yes to either question, which kind/brand did you use?

My little guy is 3 months old tomorrow, and his gas has gotten worse over the past couple of weeks. I haven't been doing/eating anything differently. His poops are fine. He just often arches his back and grunts and cries/fusses.

We give him gas drops and occasionally gripe water, and they will often give him some temporary relief, but he still has a lot of discomfort. 😞 We also bicycle his legs, etc., and maybe it's just something he needs to grow out of . . .

Thanks in advance!
