1-tier baby boy diaper cakes come with 10-15 diapers. You can get them individually or in sets. These smaller diaper cakes can be placed at the center of guest tables. Most 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 1-tier or mini diaper cakes is between $10 and $20.
