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.

I was going to say exactly the same thing - it is what we recommend to parents taking their bubs home with reflux. Just make sure that bub is at the bottom of the mattress. You can also pop a towel at the bottom of the mattress if the crib has slats, so that bub's feet don't pop through!
