Bad Economy...Bad Diapers?!!!

Today I am sad to say that I am going to have to switch brands of diapers. I switched to LUVS with Tyler after he started crawling because they seemed to hold together better, even better than Pampers, I know I was shocked myself. Just this last time I went a size bigger thinking it would help at night time. It actually made it worse!!! Both the boys the last 3 nights have wet through their diapers. Just because everyone is downsizing because of the economy, do they really have to make the quality of the diaper less too. Maybe they can save on the way they package their diapers, but don't cheat the customer on the actual diaper! So all you mothers out there what kind of diapers do you use? I am a mother in desperate need of help!!! I am thinking about buying those plastic pants to put over them at night. LOL! I'm not sure Drew would be up for that!!
