I used gripe water as well, we pretty much lived by it for the first few most of our LO's life. His poor little tummy. I'm still breastfeeding though so it wasn't about changing formulas. Also some people say to try onion water, I recommend Googling it. 😉Sounds silly, but it's supposed to work. I started incorporating more onions in my diet because I was BF.
I was recommended to try Gripe Water by several people for my son.
Also, if you are formula feeding, Enfamil Gentlease is made to help with colic, and if you are nursing, it's possible that dairy in your diet could be an issue, so you may want to try cutting it out.
