100-Day vs Full-Month Photos | When Is the Best Time to Shoot?

"Should I shoot now at one month, or wait until 100 days?"

We answer this question at least 10 times every week. The answer is actually simple—babies at these two stages are completely different people. Neither is "better"—it's about which is better for you.

📊 Full Month vs 100 Days: Development Comparison

Around 100 days, babies often show richer expressions and better head control.

🌙 Full-Month Photos Are Right for You If...

If you want livelier images, babies usually react more after the full-month stage.

• You missed the newborn window (5-20 days) and want that "just born" look
• You want to capture baby's softest, most curled-up stage (some newborn poses still possible at 30 days)
• You're planning both newborn and 100-day sessions—full month fills the gap
• Baby has a traditional full-month celebration and you want photos to match

💯 100-Day Photos Are Right for You If...

• You want photos where baby has real expressions and reactions—genuine smiles
• You want to choose from 20+ themed scenes (Safari, Bunny, Muji-style, etc.)
• You want that classic tummy time shot with baby gazing at the camera
• You're only doing one milestone session (best value for the most variety)

📅 Does a 100-day session have to be exactly on day 100?

No. The goal is not to hit the exact number, but to photograph baby when their condition is suitable.

• 90 to 120 days is usually a strong shooting window.
• If baby already has stable head control and responds well, the early 90-day range can work beautifully.
• If baby is more easily tired or slow to warm up, waiting until 110 to 120 days may be better.
• Avoid days right after vaccination, poor sleep, or when baby is unwell.

🔄 Missed 100 Days? No Problem!

• 4-5 months: Baby might be rolling over—even more dynamic photos
• 6 months: Starting to sit independently—more pose variety
• 7-8 months: Start planning Cake Smash (available from 9 months)

❓ 100-Day Photo Timing FAQ

Q: Does a 100-day photo session have to be on the exact 100th day?
A: No. Around 90 to 120 days is usually suitable. Baby’s energy, head control and daily rhythm matter more than the exact date.

Q: If I only choose one session, should I choose full-month or 100-day photos?
A: Choose full-month photos if you want a softer newborn-like record. Choose 100-day photos if you want more smiles, eye contact, themed scenes and interaction.

Q: Can baby still take 100-day photos after day 100?
A: Yes. At 4 to 5 months, babies often have even more expressions and movement. The style simply shifts from classic 100-day portraits to a broader baby milestone session.

Q: What should we prepare before a 100-day session?
A: Let baby rest and feed before the session, and bring milk, diapers, a comfort item and one meaningful outfit if you have one. The studio also provides multiple comfortable 100-day outfits and headpieces.

Q: Can 100-day photos include family portraits?
A: Yes. This stage is ideal for parent-baby and family interaction because babies usually begin to smile, look at people and respond to familiar voices.
