Is it OK to put registry information on the invitation?

Yes. For a baby shower it is expected and saves guests from asking. One short line with the store name is enough.

Whose name goes first, the host's or the parent's?

The parent-to-be. Open with who the shower is for, give the date and place, and name the hosts near the end with a contact for questions. Guests care most about who they are celebrating.

Can several hosts send the same Blast invitation?

Yes. The invite is one link, so each host can forward it to her part of the guest list by text, WhatsApp or email. There is no limit on the number of guests, and nobody needs an account to RSVP.

What to Write on a Baby Shower Invitation

What to include

The name of the parent or parents being celebrated.
Who is hosting, so guests know where to send questions.
Day, date, start time and end time.
The full address.
Registry details, or a line about gifts.
A reply-by date, and who to reply to.
Anything special: a surprise, a theme, a book request, co-ed or not.

Classic wording

"Please join us for a baby shower honoring Sarah Lopez. April 19, from 11 am to 1 pm, at 14 Willow Lane. Hosted by Anna and Kim. Please RSVP by April 10."
"A little one is on the way! Come celebrate Priya with brunch and games. May 30, at 10:30 am, at the community hall on Elm Street."
"Let's shower Rachel with love before baby arrives. March 8, from 2 to 4 pm. Hosted by her sisters."

Co-ed and couples showers

Name both parents and make it clear that everyone is welcome.

"Join us for a baby shower for Jess and Marco. June 13, at 4 pm. Backyard barbecue, partners and kids welcome."
"Baby Chen is almost here! Come celebrate Wei and Alex at a couples shower. July 10, at 6 pm."

Sprinkles, surprises and second babies

Sprinkle: "A little sprinkle for Maria's second baby. Coffee and cake, May 3, at 3 pm. No registry. Diapers and wipes are welcome."
Surprise: "Shh, it's a surprise! Please arrive by 1:45 pm. Hannah arrives at 2."
Adoption: "Help us welcome the newest member of the Carter family. Join us for a shower for Dan and Julia."
Gender neutral: "Boy or girl, we can't wait to meet you. Join us for a shower for Tara."

Registry and gift wording

It is fine to mention the registry on a shower invitation. Guests expect it and most will ask anyway. Keep it to one line.

"Sarah and Tom are registered at [store name]."
"Instead of a card, please bring a children's book for baby's first library."
"Bring a pack of diapers in any size for a chance to win a prize."
"Your presence is the only gift we need."

When to hold it

Most showers happen a month or two before the due date. That is late enough to feel real and early enough that the parent-to-be is still comfortable.

Guests need time to shop from the registry and some will travel, so a shower invitation goes out earlier than a birthday one: four to six weeks ahead is the usual window.

Tips from the host's side

Check the guest list with the parent-to-be, unless it is a surprise. Then ask their partner or a close relative.
If there are several hosts, put one phone number on the invite for questions.
Two hours is a good length. Three if you are serving a full meal.
Say what food to expect: brunch, lunch, or cake and tea.

Sending it as a video invitation

A shower guest list usually spans generations and cities, and it is often split between two or three hosts who each know a different part of it. Blast makes an animated video invitation with music that goes out as one link, so every host forwards the same invite, and guests RSVP from it without an account. That gives you a head count before you order the food. Blast is free to create and send.
