How did you change oz per day?

Bexxy10

I'm about to hit the 9 month mark with my little Bean, and I'm going to try and make the change from around 5-6 5oz sippy cups to 3 7-8oz sippy cups a day.  If you're on this track how did you make the transition?  We are on 3 solid meals a day, although dinner has been trying.  She eats great at school, but at home refuses purees and has become very selective on what solids she will eat, which also changes daily.  Also what times are you doing your liquid feedings?
