I'm sorry I never replied, your response was super helpful thank you! So it turns out my son does have mild reflux and colic
He is also intolerant to dairy as well *sigh*. I'm off dairy and he's on meds for the reflux which is helping but we just have to ride out the colic I guess...
On the brightside his nights are for the most part pretty good, he only wakes up a couple of times. We started sleeping him on his belly and that seemed to make a huge difference!
