Protocol for a "Dutch-treat" party calls for guests to pay their own way. A Dutch-treat baby shower invitation should politely inform guests they are responsible for a portion of the party's costs. While etiquette does not advocate asking guests to pay to attend a party, a Dutch-treat baby shower requires it. According to the LifeTips website, the best place to provide cost-related information is in the corner of the invitation.

Lead the invitation with a cute poem or rhyme. Follow this example from the Creative Baby Shower Ideas website, "Bring your rain boots, bring your umbrella/Come celebrate a new little fella."

Include an announcement about the nature of the party. For example, "Please join us for a Dutch treat baby shower honoring [Mother-to-be's Name Here]."

List other relevant details about the baby shower, such as the date, time and location of the event.

Ask guests to confirm their attendance at the baby shower. Include the following language on the baby shower invitation: "Kindly reply by [month, date]." Provide a telephone number guests can call to R.S.V.P. .

List the estimated cost per person. Print this information using a smaller font size. Place the text either in the corner of the baby shower information, or directly under the wording from Step 6.

Provide details about the mommy and baby-to-be's gift registry at the end of the baby shower invitation. For example, "Registered at Baby Boutique."
