my little boy has it he's 6 1/2 month old he gt it around 3 months we got given gavison that didn't work got given quite a few things nothing worked we took him to a children's walk in centre as my doctor is absolutely shocking and they said they wanted to try him on cow and gate carabel and it's fab all it is a thickener it's the new thug they give out but alot of the GPS don't really know about it we had to tell me gp about it so give that a try first you can also buy it without prescription it's around £5 because it's quite new alot of pharmacys don't have it and will order it in for you maybe get a box and try it if it works get it on prescription x
