Helping baby with reflux

Pretty positive my baby has mild reflux, but its not confirmed by his pedi yet. I'm not worried at this point because he has plenty of wet diapers and he is gaining weight. But he is definately uncomfortable with the grunting and congestion, especially at night.

I was wondering how do you help your baby with the symptoms?

So far we have short, frequent feedings, I prop him up for a few minutes after feeding, then burp. I also keep him upright after feeding for about 15 minutes.

I was wondering if there is anything else you find helps your little one?
