For the small cost of bottled water I'd prefer to err on the side of caution. Since it's the Dry Season there you're probably pretty safe but it wouldn't be at all sensible to use tap water for washing bottles or cups used by babies or small children in the Wet Season.
I wouldn't (and didn't) risk my small child's health by using tap water at any time of the year in Bali. What you do is up to you, of course.
I highly recommend using bottled water & sterilising tablets/solution.
