Gripe water and Zantac

C.L.S • 😃
I been using colic calm for my boy and it's been working but sometimes it doesn't. I guess you can say it's a hit or miss. My boy is very gassy and is colic as well. The doctor wants him to go on Zantac too. Has anyone had their little ones on Zantac ? Also, what is a good gripe water? Thanks 😃😃
