I have 2 girls, both with reflux, although Alex’s was really mild and easily controlled with zantac. My MIL says dh was a happy spitter – spitting until he was about a year old. I was a “colicky” miserable baby until I was almost a year old. I only slept for a couple of hours at a time and usually had to be held or driven around in the car in order to get me to sleep.
I still have reflux issues (and a hiatal hernia) now. I’m on prilosec. My siblings didn’t have reflux as babies, but my brother has horrible reflux now. My parents both had reflux. We grew up thinking that all adults popped tums regularly.
