2-tier baby girl diaper cakes come with 20 - 30 diapers. You can get them individually or in sets. These medium diaper cakes can be placed at the center of guest tables. Some have the option to be single-sided or double-sided. Single-sided means the back of the topper will be blank and only the front of the diaper cake will have a bow or cutout. Double-sided means what you seen on the front will be on the back. Standard price for 2-tier small diaper cakes is between $20 and $22. Standard price for 2-tier medium diaper cakes is between $30 and $32.
