The one thing I was told with having a reflux bub is positioning. Maintain their beds at an incline where their head is 25% higher than their feet. So with our cot we rolled up a blanket & popped it under the top end of the cot & put her at the bottom of the cot. Also for the first 30 minutes after each feed they need to be more inclined to help push that food down into the belly more.

Matilda had silent reflux and would often regurgitate if laid flat. It was awful to listen too.
