I posted this in response to your FB post, but figured I’d share here in case it’s helpful to anyone.
My boy has a tendency to stop drinking when the weather gets very hot or very windy, and he’s colicked several times as a result.
After the last colic a few years ago, I started putting an inch of apple juice in a small bucket and filling it with water, then giving it to him after every ride as a treat. I always use the same red bucket and that color bucket is never used for anything else.
Now, he starts to lick his lips whenever he sees the bucket and if he stops drinking, I know he’ll always drink the apple juice water from that bucket. No more colics, touch wood!
