The Esbilac should be reconstituted with plain water. Sometimes tap water, though safe for humans and pets (dogs & cats) there can be high enough levels of trace elements or metals that are very hard on these tiny, fragile bodies. I have worked with folks across the country that had issues (some very weird in deed) that were resolved by switching to bottled water (never distilled water).
The temperature of the hydration and / or formula can make a huge difference in their "pickiness". They like it very warm, warmer than we'd think (like ~108F).
