misty with Matilda before we tried anything we worked on positioning, so we kept her at an angle at all times. For the 30 minutes post bf we would hold her in a sitting up position, as well as propping her cot up with a blanket rolled up under the mattress at her head end.

The only other thing that may help is something like Infants Friend, its supposed to help reflux too. We tried that with Matilda just before the Mylanta.

I would definately go to your Dr as soon as possible as they can help decide what the best course of action would be.
