Gee, I remember the days when I saw Evan in his crib sleeping with his neck tilted all the way back and I had NOOO idea why - then everything came together - bad feedings, weird gurgling in throat, unexplained crying, and my excessive Googling..I had to hold him upright ALL the time, to get him to nap..it was so sad.
We were told it was reflux and he'd grow out of it- but it got worse and worse..finally we insisted on Zantac..which definitely seemed to help! That was when he was like 2.5 mos old.
I started weaning him off at like 4 mos, just to see..and he definitely had grown out of it. He was the same off it as on it. I dont know now if its the meds that helped or just him getting older - I think for really serious cases meds shd be used - but I sometimes regret as a first time mom my rush to help him with meds..So, as far as weaning, I'd give it a try when your baby can sit up a lil more - when the milk can stay down better.
Evan's almost 6 mos old now - and the reflux that was a horror then - is gone. He's a happy lil spitter sometimes, but that's bound to happen.
