I feel like if DS were really little, I'd probably be more cautious and think about buying nursery water or something, but he's 7.5 months old. Our NP said to use a Brita pitcher with tap water at home, so that's what we do, but we're going to FIL's house for Thanksgiving this week, and I'm not sure he has any kind of filter. So now I'm wondering if I should just not worry about it and use tap water, or if we should buy a filter or bottled water or something.
What do you all use?
