The right time to send a baby announcement is when the family is ready to share the news. A mailed card can arrive after close family and friends have already heard directly. Treat timing advice as permission to plan, not as a deadline during an unpredictable season.
Tell close people directly first
Decide together who should hear from you by call, text, or personal note before a wider mailing or public post. That can avoid a close relative learning important news from a card after everyone else. You may also choose to keep the circle small for a while.
Emily Post's birth-announcement guidance allows families several months to send formal announcements and says it is never too late to share the news. Use that as a reminder that there is room for recovery, rest, and changing plans. The guide is a convention, not an obligation or a medical timetable.

Prepare only what stays true
Before the arrival, you can organize an address list, choose a design, and decide who will review the proof. Leave the baby's name, dates, measurements, and photograph as blanks until your family chooses what to disclose. Avoid ordering a finished message that depends on facts you cannot yet confirm.
Set a modest mailing plan: who can help address envelopes, when a proof can be checked, and whether you want paper, email, or a personal call. A helper can assist with logistics while the family remains in control of the wording and recipient list.
Allow for printing and postal time
If you choose mailed cards, check the seller's current proof and production information for the exact order when you are ready; these vary and are not guaranteed here. USPS says First-Class Mail is generally delivered in one to five days but does not guarantee arrival on a specific date. Avoid promising recipients a delivery day.
Before posting the full batch, weigh a complete card and envelope. Unusually shaped, thick, or rigid pieces may need different postage. A correct address and return address are more useful than rushing to meet an etiquette target.

Handle news that is already known
If close friends already know, a card can still be a keepsake, but it need not repeat a gift request or make them feel obliged to respond. Emily Post cautions against treating announcements as gift solicitations. You can send a personal thank-you to someone who has already offered help rather than adding that person to a bulk message.
Original follow-up wording: 'We wanted to share this little update with you in a card, even though you have already welcomed [Name]. Thank you for caring about our family.' Use it only if it fits the relationship and the family wants another note.

Give yourself an exit ramp
If months pass, send the news in the form that is easiest now. A current photograph, a short note about how the family is doing, or a simple greeting may feel more natural than pretending the card was mailed immediately after birth. Review the final message for privacy and accuracy, then let it go.
- Choose the first circle.
- Confirm what is safe to share.
- Proof before ordering.
- Check the assembled mailpiece and postage.
- Send when ready.
