Uy, for health and safety questions tulad nito, mas better na i-ask mo directly ang doctor or nurse ha, lalo na kapag may sakit ang baby, they'll know best what's safe. But from what a few of us moms talk about, ORS solutions can change after a day or two once mixed, so mas safe talaga mag-prepare ng fresh batch para sa lo mo. Better safe than sorry diba, especially with hydration ng babies!
