Do you really have to give your baby "nursery water"?
You can begin giving your baby drinks of water around six months old and shouldn't give an excess of eight ounces per day until after eleven months old. Then you can offer the baby some water throughout the day as needed but still be cautious not to give too much.
By twelve months old, your baby will be having a variety of fluids every day (milk, water and juice) but none should be in excess. Too many liquids can cause a lot of discomfort in your small baby's body.
From the time of birth however, you are still going to need to use water to mix with powdered formula if you use it supplemental to breastfeeding or instead of breastfeeding.
Should you use a specific type of water? When you see the bottles of "nursery water" on the supermarket shelves, with the picture of the baby on the bottle, do you wonder if giving your baby that water is really the best thing? Does it matter?
Recently, many pediatricians have been recommending that nursery water is not necessary but rather than using an all natural spring water like Poland Spring or Deer Park, it might be best to use municipal tap water as an alternative to the nursery water. This is because the municipal water can offer the proper amount of fluoridation for the baby's developing teeth, as the nursery water would.
The thing about this is that if you offer your baby municipal tap water and report this to the baby's pediatrician when asked it is possible that the baby will then need a finger prick to test his or her blood for lead. Therefore, with this precaution needed there is still some albeit small risk of lead getting into the baby's system from the tap water.
In my opinion, you should either stick with the store bought nursery water or be sure to use a filtration/ water purification system on your tap even if you live in a city or county that reports that the municipal water is safe to drink without having to use a filtration system.
