Hi, my little one is now 4 weeks old she had colic and we used infacol after 2 weeks she was spitting it out and was unsettled (was on c&g first infant milk) and she always spit up some formula or sometimes projectile vomited it, HV thought could be reflux tried on anti-reflux c&g which helped her keep feeds down but colic played up now and then but after a week she became constipated so changed milk back to first infant now shes bringing feeds up again ( got gaviscon from GP again doesnt agree with her tummy), changed bottles to dr browns seem to help colic.

Is there any formula which is slightly thicker the first infant but thinner than anti-reflux?

Thanks.
