If you have good tap water, just run it for a few seconds to flush the pipes, then use it. If you’re nervous, boil it and cool it. If you want to buy a fancy jug, do it. Your baby is going to be fine either way.
Honestly, the biggest risk is not the water—it’s mixing the formula wrong. Follow the instructions on the can. No extra scoops. No “I think this looks right.” Your baby’s kidneys are not a math problem.
So go ahead, make that bottle. You’ve got this. And if you still feel confused, call your pediatrician or text a mom friend. We’ve all been there, holding a bottle and staring at the faucet like it holds the secrets of the universe. Spoiler: it doesn’t. But you’re doing great. Now, where’s my coffee?
