Tips on consolidating baby naps?

My daughter is 7 months old and she loves to cat nap. I've been trying for 2 months to consolidate her naps. She still naps 4-5 times a day and only sleeps for 30 minutes at best. She's had the same sleeping pattern for the past 2 months - as in she takes naps at the same time, buy they keep getting shorter and shorter!. I try to push back her morning nap to an afternoon nap, but she screams bloody murder. I've even seen her fall asleep while sitting and even while holding onto our couch and standing. Any advice?
