We have been feeding my 6 week old Kendamil ready to feed formula bottles. We are wanting to switch over to the powder but not sure what type of water to use at this age. Can I just use bottled spring water to prep the bottles or do I have to use boiled water and let it cool?

I think I read we can just use regular tap water by 4 months old - just wondering how we can do it for the next couple months. I live in Ottawa in case that matters!
