Did you continue using them through size 6, or did you switch to another product at some point? And if so, which one. We've switched to baby dry at night (just the regular ones), and really like them. I'm thinking of switching from Swaddlers to baby dry. The blue line was great in the beginning, but we do just fine without it. She's 7 months tomorrow, and not crawling yet so I don't see us moving into cruisers just yet!
