I was meaning really that I think the grunting got better with time, but DS3 became a difficult feeder due to reflux and the gas was unbelievable at times. Because of this we ended up with major sleep problems (waking every 45 minutes to 2 hours). We had him medicated and I tool dairy, soy and wheat out of my diet. Add to that, teething, which is extra hard on refluxers, and well, our first year was very tough with regards to sleep. Although I had intended to have him sleep trained early I wasn't able to do that as he was so uncomfortable. Then it becomes difficult to determine what is AP and what is truly discomfort. Anyway, I don't want to scare you. I think some people with refluxing babies don't have as much trouble with sleep. DS3 did outgrow it by the end of the first year or so. Once we finally got him falling asleep independently at 13 mo, things improved significantly at night. But, as it turns out, ds# can protest very loudly and 'learns quickly' (i.e., picks up bad habits quickly when we have to AP due to illness and teeth).
I do know that DS3 always needed to be burped properly after all feeds. If not, he would wake if asleep when I set him down. And/or he would grunt and fuss until the air was out.
