Losec wont stop the vomit, but it will decrease the acid content in the vomit so that it doesn't burn.

All kids are different when it comes to reflux, some outgrow it at 2 months and most have outgrown it by a year. I generally wait until things are pretty steady and then try and wean it, you can try and cut down the dose a little bit and see how it goes.

Just remember as they grow the symptoms change, so you may be looking at things like food refusal, bad sleeping as well as being irritated and crying.

Good luck!
