Plan a Thank-You-Worthy Party

Pro Tip

Send thank you notes within 1 week of the party. Kids over 5 should write (or draw) something themselves — even just their name. The secret: take a photo of each kid with their gift AT the party. Attach it to the thank you note. Parents love this and it takes 10 seconds per kid.

Frequently Asked Questions

What should I write in a birthday party thank you note?

A good thank you note has 3 parts: (1) Thank them for coming to the party, (2) mention the specific gift and how much your child loves it, and (3) close with warmth. Keep it short — 2-4 sentences is perfect. Personalize each note by mentioning the actual gift rather than sending generic cards.

How soon after a birthday party should I send thank you cards?

Send thank you notes within 2 weeks of the party, ideally within 1 week while the memory is fresh. For kids' parties, even a simple text or message to the parents within a few days is appreciated. Handwritten notes make the biggest impression but are not required.

Should kids write their own thank you notes?

Kids 5 and older can sign their name or draw a picture on the card. Ages 7-8 can write a sentence or two with help. By age 10, kids can write the full note with a parent reviewing it. For younger children, parents write the note and the child adds their name or a sticker.

Do I need to send thank you notes for a kids birthday party?

While not strictly required, thank you notes are strongly recommended — especially when gifts were given. They teach children gratitude and make gift-givers feel appreciated. At minimum, send a thank you text or message to each family. Physical cards are ideal for larger gifts from close friends and family.

How do I write a thank you note for a gift card or money?

For gift cards and money, mention what the child plans to buy: "Thank you for the gift card — Emma is so excited to pick out a new book!" or "Thank you for the generous birthday money — Jake is saving up for a new LEGO set." This makes it personal and shows the gift will be put to good use.
