Sorry i didnt get back to you sooner... Weleda colic powder is from health food shops. Most big ones will have it.

My dd has silent reflux too an she has hiccups a lot, you can hear her gurgle and choke a bit then wake up screaming she is really unsettled all the time and hated tummy time! She is on zantac but thinking her dose needs to be increased cause she is much bigger than when she was first diagnosed.
They tried her on gaviscon infant first but it just consipated her so we went onto zantac.

Good luck sweets and def see your gp!
