Water Used to Mix with Powdered Formula

What kind of water are you supposed to use to mix with powdered formula? Purified? Distilled? ?? My husband bought distilled...is this ok? It is at room temp...we're not supposed to warm it, correct?

What can I do next?

So What Happened?™

Saw the pediatrician today and asked about this. She recommends using purified water, boiling it to sterilize it (do this until baby is 7 months old) and then store in glass container. She had concerns about any kind of water (nursery, distilled, etc) that is stored in plastic containers (due to chemicals and BPA). She said I can mix the formula ahead of time and store in the fridge up to 48 hrs. Then warm to room temp. She said when the baby is older and the digestive system is more developed he could handle formula out of the fridge.
Thanks for all the replies and advice!!

If you are in Chicago, unless you are in an old building with bad pipes, then tap water is just fine to be honest---no need for bottled water. As for temp--whatever is easiest for you. I would do room temp if the baby doesn't mind it, less hassle with warming it up, especially if you are out some where =)

I suggest not using distilled because distilling removes elements such as oxygen, that contribute to flavor. Taste it and you'll understand. Tap water is fine. Some parents prefer to use filtered or purified water. If you drink filtered water, use filtered for your baby.

The down side of using filtered water is that we're not exposing them to tap water, which at some age they will be drinking. The more we "protect" our babies from exposure to ordinary things we are decreasing their bodies abilities to build up antibodies to protect them from exposure to the things that are in the environment that we cannot avoid. Studies have shown that the baby and child who is not allowed to crawl on the floor or play in dirt, or drink tap water, etc. are less healthy than those raised the "old" way in which exposure was not so much of a concern. My daughter's sister filtered her babies water, shampooed the rugs weekly, mopped hard surfaced floors several times a day, kept them away from anyone with a cold or who appeared ill and her babies were sick all the time. My daughter didn't do any of those things and was not concerned about exposure of anything except for chemicals and her babies were healthier.

We do have chemicals to which we do want to limit exposure but unless your city does not do a good job of clearing out pathogens there is little need to not use it for formula. There is some legitimate concern for flouride too. If you drink filtered water, then it makes sense to filter your baby's water because they will continue to drink filtered water after they're weaned. But if they will continue to drink filtered it makes sense to start with filtered.

Use whatever temperature of water that your baby prefers to drink. Yes, we are told to not microwave formula or breast milk for baby. The reason is that the microwave heats unevenly. They have to tell us to not microwave it because of liability concerns. There are some people who do not use common sense. If you shake the bottle a minute or so before feeding it and then test the temperature on the inside of your wrist there is not danger that your baby will be burned.

If you're using water out of the fridge, you can heat it first in a measuring cup, so that it's easy to pour, and then pour it into the bottle containing powder. If you're going to be away from home for awhile you can put heated water in a thermos and the formula in bottle(s) to be mixed later. That way you don't need to be concerned about the formula spoiling.

Most tap water is fine, as long as there's no floride in it (you can look up online if your local water has floride). We have a water filter in our fridge, and used the water out of there. Ideally, formula should be body temperature (like breastmilk obviously would be). So slightly warm but not hot to the touch. You can run hot tap water over the bottle for a couple of minutes and that will usually do the trick. Some babies are fussier than others--my daughter would be fine with room temperature or even cooler, as long as it wasn't actively cold, but every child is different. Do be careful to do too hot, however--if you warm it in a pan or microwave, be sure to shake the bottle to mix the temps, then test on your inner wrist first, to make sure it's not too hot.

When we mixed formula, we just used the filter on our tap. We would also use Brita or any other filtered water. It is less expensive than distilled, and it is safe to drink. If you would like to use it cold, at room temp, or warm, they are all fine. Our son took his formula either right from the refrigerator, room temp, or warmed up... he didn't care. The reason for warming the formula up is to make it easier on their tummies.

Good luck! I hope this helps.

I always use nursery water with my kids. It has that added fluoride they need for their teeth. And I know they don't have teeth out yet but I have read that their teeth under the gums still need it. I don't recomend tap water because where I live there are just too many boil water notices. I don't like that and I feel tap water is not safe. My older child who is 3 drinks drinking water now and my child who is almost 2 drinks nursery water still untill she turns two because she doesn't use fluoridated toothpase yet. My kids go to a nursery so they are already exposed to many germs so I don't want to add to it by using possibly contaminated tap water to it also. I never refrigerated their water before age 1 and also I stopped warming it after about 4 months old.

i used purified water because i have well water. i was specifically told NOT to use the water with added flouride as this would be too much for infant & will cause chalky white & brown stripes to develop in permanent teeth. As for temperature, well, I never heated mine just left at room temp it just seemed to be easier. especially when your out & about. I used distilled for awhile before I realized that it is not recommended. So, you could probably use it if if you need to, but wouldn't long term. Best of luck.

I don't think you are supposed to use distilled. The minerals in tap (or even purified) are actually good for most kids. (An exception may be sick kids with weak immune systems or something--in that case I'd ask the doctor).

Warming it is just more work for the parents; I never did for either of my kids. (It was room temperature.)

Use purified or distilled water.

Tap water is not even that great for adults. Do you have any idea how much chlorine and heavy metals are in tap water? Even if they tell you it's okay to drink - it's at safe levels. They tell you that so you won't freak out if you really knew what you were drinking or bathing in.

If you are in Chicago, unless you are in an old building with bad pipes, then tap water is just fine to be honest---no need for bottled water. As for temp--whatever is easiest for you. I would do room temp if the baby doesn't mind it, less hassle with warming it up, especially if you are out some where =)
