Thanks, Jacob, for reaching out to Pampers and sharing that your little one isn't fitting well in the Pampers Swaddlers you purchased. It may help to know that our Quality Team, over the many years we've worked with families, has discovered that many babies are in the wrong size diaper, in fact, up to 30%. That's why our sizes cover a weight range, because some babies, although heavier than others, have a slighter frame. If your little one's diaper isn't snugly fitting them, it may be helpful to pick up a pack that's a size smaller than your current one. We'd be happy to help with that, and hope you'll call us any Monday through Friday, from 9 AM to 6 PM, EST. Our number is 1 (800) 726-7377.
