100 Days Baby Rituals Around the World: Japan, Korea & Beyond (Plus Gift Ideas)

The first few months of a baby's life are filled with milestone moments, the first smile, the first giggles, and the end of the tiring fourth trimester. Historically, surviving the first 100 days was the biggest milestone of all.

Ancient cultures viewed 100 days as the critical threshold where a newborn’s fragile immune system stabilized and the mother recovered from childbirth. Across Asia and parts of the West, the 100-day mark remains a deeply symbolic transition from survival to celebration.  

Why the 100th Day Is Globally Significant

In ancient times, infant mortality rates were high due to disease, lack of sanitation, and seasonal harshness. Keeping a baby indoors during their first 100 days was standard practice to shield them from illness.  

Reaching day 100 marked a major milestone:

• Medical Survival: The baby survived the most vulnerable phase of infancy.  

• Mother's Recovery: The mother’s initial postpartum period ended, allowing her to rejoin social life.  

• Symbolic Completeness: In Asian numerology, the number 100 symbolizes longevity, perfection, and wholeness.  

  
  

100-Day Rituals Around the World

Japan: Okuizome (The First Weaning Ceremony)

In Japan, the 100-day milestone is marked by Okuizome (first eating ritual). Because babies cannot eat solid food at three months, a designated family elder uses chopsticks to gently pretend to feed the baby ceremonial foods.  

• The Feast (Iwaizen): Consists of Sekihan (red bean rice for good fortune), whole grilled sea bream (Tai), clear soup, and pickled vegetables.  

  
  

• Tooth-Hardening Stone (Hagatame-ishi): A smooth stone is touched with chopsticks, which are then touched to the baby’s gums. This custom symbolizes strong teeth and robust health throughout life.  

  
  

• Gendered Lacquerware: Boys are served food in red lacquer bowls, while girls are served in bowls that are black outside and red inside.  

  
  

South Korea: Baeg-il (Celebrating the 100th Day)

The Korean Baeg-il is one of the most recognized baby celebrations worldwide.

• The 100-Person Rule: Tradition holds that if Baekseolgi (pure white steamed rice cake) is shared with 100 people, the baby will live a long, healthy life.  

  
  

• The Symbolic Table (Baegil-sang): The table features white rice cakes (purity/100 years), red bean cakes (to ward off bad luck), and five-colored rice cakes (harmony).  

  
  

• Attire: The baby wears a colorful Hanbok. Modern parents typically take professional milestone photos featuring styled backdrops.  

  
  

Iceland & the Nordic Region: The 100-Day Naming Custom

While Nordic countries do not hold a literal "100-day" party like East Asian nations, they maintain a tradition tied closely to this timeframe.

In Iceland and surrounding Nordic regions, babies are rarely named at birth. It is customary to wait up to three months (roughly 90–100 days) before revealing the child's name to the public.

• The Reveal: The name is officially announced during a family gathering, standard baptism, or secular naming ceremony (Nafnagift).

• 
  

• The Origin: Historically, waiting 100 days allowed parents to observe the baby's emerging personality before choosing a fitting name.

  
  

Modern 100-Day Celebrations: Old Traditions, New Styles

Modern parents are bringing a fresh look to 100-day rituals:

• Themed Milestone Photo Shoots: Studio portraits featuring 3D text spelling "100" are replacing larger banquets.

  
  

• Hybrid Gatherings: Families combine elements from different backgrounds, serving Baekseolgi alongside modern cupcakes or party favors.  

  
  

• Eco-Friendly Gifts: Digital gift funds and personalized heirloom jewelry (like engraved silver bangles) have largely replaced physical toys.

  
  

Celebrating 100 days offers a sweet spot: the baby is more alert, starts smiling for pictures, and parents have adapted to their new routines. It is a celebration of resilience, heritage, and the journey ahead.

Meaningful 100-Day Baby Gift Ideas: Traditional & Modern Choices

Attending a 100-day baby celebration or looking for the perfect gift to mark this major milestone? Because reaching the 100th day symbolizes longevity, health, and a smooth transition past the newborn phase, gifts traditionally focus on prosperity, protection, and lasting family memories.

Whether you want to honor cultural roots or pick a practical favorite for new parents, here is a complete guide to 100-day baby gifts.

Traditional Keepsakes with Deep Cultural Meaning

In many Asian cultures, gifting precious metals at 100 days is a way to wish the child financial stability and a long life.

• Gold Rings and Bangles (Korea & China): In South Korea (Baeg-il) and China (Bai Ri), family members gift 24k gold rings (Dolbanji) or delicate bangles. Pure gold represents good health, wealth, and lasting security for the baby's future.

  
  

• Silver Engraved Spoons or Rattles: A classic Western and international staple. Gifting a personalized silver spoon plays on the idea of being "born with a silver spoon," symbolizing a life of abundance.

  
  

• Longevity Lock Pendant (Bai Sui Suo): This traditional Chinese silver or jade lock necklace is designed to symbolically "lock" the child to life, guarding them against bad luck and illness.

  
  

Practical Essentials for the Next Developmental Phase (3–6 Months)

By 100 days, babies are graduating from sleep-all-day newborns to active, alert infants ready to explore their surroundings.

• Teething Toys & First Feeder Sets: Since 100-day rituals like Japan's Okuizome center around food and solid eating, food-grade silicone teethers and mesh fruit feeders make thematic, highly useful gifts.

  
  

• Developmental Gyms & High-Contrast Books: Around month three, babies begin tracking objects and using their hands intentionally. High-contrast sensory toys and play gyms support tummy time and cognitive growth.

  
  

• Sized-Up Clothes (6–12 Month Range): Babies grow out of zero-to-three-month sizes rapidly. Gifting organic cotton bodysuits or traditional wear, such as a baby Hanbok or Kimono romper, for their next stage keeps parents prepared.

  
  

Modern Keepsakes Parents Will Cherish

• Milestone Photoshoot Voucher: Capturing a 100-day baby, full of smiles, rolls, and bright eyes, is a gift parents treasure forever.

  
  

• Clay Impression & Footprint Kits: A simple DIY frame kit lets parents lock in the exact size of their baby’s tiny hands at the 100-day mark.

  
  

• Custom Nursery Name Art: Particularly fitting for Nordic or Western celebrations where a baby's name is revealed around the 3-month mark, custom wooden name signs make a thoughtful bedroom addition.
