Just to back up the other comments, I used a tealight holder for water from day 1 with my daughter because of the horrors I had when trying to wean my son off boob then bottle. At nearly 8 months, about 75% goes into her mouth. I follow a tip from Montessori education - have the water/juice in a separate bottle and only pour enough into the bottle to wet the bottom of the glass each time she empties it (down throat on or elsewhere). Baby gets enough to practice and both of us end up only moderately damp instead of totally drenched!
