We do a lot of size exchanges, so every couple of weeks it is necessary to go through all of the baby slings sent back to us, inspect, press, fold, occasionally resize, and then add them back to our inventory. This can take a couple of hours. Occasionally there is a sling found that isn’t resellable. These are either sold to distributors cheap as “demo” slings, or donated to www.NoMotherLeftBehind.com .
