We don't use a sling or a carrier. DH has a shoulder issue that precludes his using one, even the Ergo, which we own, and I have the hugest chest you can imagine and have never been able to use the Ergo. I also have a lingering back problem I would not want to exacerbate at Disney! Since we can't use a carrier, and we can't use strollers in the line, what do we do with heavy and squiggly 11 month old DD? For most rides, we'll want to take her on, and for those where we don't want to take her, we'll want to do a baby swap. If we have to hold her while we wait in line for hours, this trip will be miserable!!! Please tell me there's a solution.
