Didn't all or some of your kids have a milk sensitivity (and maybe wheat as well?) What were their symptoms? How long after giving up dairy did it take to see improvement? How long did you have to alter your diet and how strict were you about it?
Matthew is having some reflux symptoms, spitting up a lot and some of the time he is a "happy spitter" but sometimes he cries and seems like he is in pain.

It could be GERD but I know I've read it could also be a food sensitivity, which is usually dairy so I gave up dairy about 3 days ago. I haven't seen any improvement yet.
