Plugs and rings are now optional separate purchases from the kits. If you want them, you must purchase them separately.
The required plug & ring sizes have occasionally varied from one production run of the kits to another. This sometimes means that a listed plug might fit that particular baby loosely, and sometimes means it fits tightly. If it is tight, try heating the vinyl before inserting the plug. If it is loose, secure it with a strong glue such as E6000. We recommend that you always keep a range of sizes of plugs & rings on hand in case that happens, and buy extra. That way you can also try the next size if you have a problem. We have priced the rings and plugs very cheaply to allow you to buy extra and to experiment.
(The number in parenthesis is the Bountiful Baby item number for that plug or ring.)
