Feeding, sleep, and diaper notes end up in too many places
At 3 AM it's hard to remember the last feeding, the next nap window, or what your partner already logged.
This is Sunny
A tiny sprout with a big mission: to help parents keep their baby’s first years as a warm story, not a chaotic mess of notes.
Sunny lives inside Sunny Seed — your baby tracker, diary, and AI assistant for sleep, feeding, growth, milestones, and memories.
What usually ends up in too many places?
Growth and milestones create guesswork
Parents want WHO-based growth context and age-appropriate milestones without turning every search into an anxiety spiral.
Photos are saved, but the story is missing
First smiles, first words, and tiny wins end up as photos, videos, and notes instead of becoming a baby diary your family can revisit.
Sunny Seed — a baby tracker, newborn diary and AI assistant in one
One place for daily care, development and memories: trackers, diary, WHO growth charts, milestones, vaccinations and family access.

Hi! We're the family behind Sunny Seed
Sunny Seed was created by parents — for parents. We know what it's like: sleepless nights, counting feeds, tracking sleep and wake windows — and being afraid to miss what matters most, all at once. When our daughter was little, we recorded everything about her in different places — phone notes, different apps, photos in the gallery, albums, social media. We wanted to keep every little thing.
And then we thought: what if all of it lived in one cozy place?
That's how Sunny Seed was born. We built it the way we wanted to use it ourselves — so your baby's first years are kept safe and in order.
We're sharing it with you — warmly, with all our heart. 🌱
“The first year will not repeat itself. Keep the care, growth and memories in one gentle place.”
