Great News folks! I’ve just discovered that as Lo-Lo’s over 6 months old, she no longer needs to drink cooled boiled water. She can now drink water straight from the tap in the UK! In a way this is a relief as she’s been secretly drinking bath water for some time.
NHS also point out rather interestingly:
Bottled water is not recommended for making up infant formula feeds as it is not sterile and may contain too much salt (sodium) or sulphate. If you have to use bottled water to make up a feed, check the label to make sure the sodium (also written as Na) level is less than 200 milligrams (mg) per litre, and the sulphate (also written as SO or SO4) content is not higher than 250mg per litre. Bottled water is not sterile, so it will need to be boiled like tap water before you use it to prepare a feed. Always use boiled water at a temperature of at least 70ºC, but remember to let the feed cool before you give it to the baby.
