So my son has acid reflux?

And my doctor does NOT give medication for it. My son is 10 1/2 months and does not sleep well at night. He will be up anywhere between 2-10 times per night. I am wondering, does anyone know of any natural remedies to help in the night with the reflux? I do feel this is why he can't stay asleep for very long periods of time (he used to only wake up once when he slept in his car seat for the first few months - his doctor suggested it - and after we started laying him flat it has been bad). I took him to the chiropractor today so we will see if that makes any difference. Also, he tends to cough for a little while when he first goes to sleep and then it's like he coughs everything out and is fine - it's a phlegm cough. Does anyone know anything to help?
