What do you need right now?
Three things, each matched to how babies actually grow
Sleep sounds (from birth)
Hour-plus lullaby and brown-noise long-plays. Audio-first on purpose: steady sound is the evidence-backed part, so our visuals stay dark and still, and we tell you to dim the screen.
The science of baby sleep →High-contrast cards (0–6 months)
Bold printable patterns sized for what newborn eyes can see — because the research on high-contrast play is about physical cards during awake time, not screens. Print them free below.
Download the card sets →Toddler learning (ages 2+)
Short, slow videos that teach one thing at a time, pause so your child can answer out loud, and invite them to stand up and move — the format the preschool-media research supports.
How little minds grow →Printable high-contrast cards
Newborn vision is roughly 20/400. In the first months, babies see large, bold, high-contrast patterns best — classic looking-time research (Fantz, 1961) shows they gaze longest at strong contrasts and simple face-like shapes. These are physical cards for supervised awake time, not screen content. Five free sets: two classic pattern sets, and three that match the sensory videos figure for figure, so a baby meets the same owl or sun on paper and on screen.
Set 1 — Black & White from birth
- 13 bold patterns: stripes, bullseye, checkerboard, simple face, moon, sunburst and more
- One large pattern per page — hold 8–12 inches (20–30 cm) away
- No signup, no email, no watermark
Set 2 — Black, White & RED from about 3 months
- Red joins the patterns once color vision arrives — red is typically the first color babies see
- Ladybug, heart, flower, big red circle, red bullseye, black-and-red stripes and more
- No signup, no email, no watermark
Set 3 — Animals from about 3 months
- 15 friendly animals in black, white and red — owl, fish, ladybug, penguin, elephant, turtle, cat, bird, bunny, whale, snail, butterfly, octopus, bee, caterpillar
- The same figures as the Animals sensory video, with the name under each one so you can point and say it
- No signup, no email, no watermark
Set 4 — Garden & Sky from about 3 months
- 15 garden and sky friends — sun, flower, cloud, apple, star, mushroom, umbrella, cherries, moon, tulip, kite, strawberry, tree, balloon, leaf
- Matches the Garden & Sky sensory video figure for figure, name under each one
- No signup, no email, no watermark
Set 5 — Shapes & Patterns from about 3 months
- 8 shapes with friendly faces and 7 bold patterns — circle, stripes, square, spiral, triangle, checkerboard, heart, pinwheel, diamond, target, hexagon, zigzag, oval, dots, cross
- Matches the Shapes & Patterns sensory video, name under each one
- No signup, no email, no watermark
- Print on white Letter/A4 paper or card stock.
- Hold a card 8–12 inches (20–30 cm) from your baby's face during awake time, such as tummy time.
- Name what you see — "stripes!", "red!" — your voice is part of the fun.
- Swap cards when your baby looks away; looking away means "done for now."
- A few minutes at a time is plenty. Always supervised, never during sleep.

The science of baby sleep
Why newborn sleep looks nothing like yours, what steady noise actually does, how loud is too loud, and why we keep sleep visuals dark and still.
Read the sleep guide →How little minds grow
What newborns can see, why talking beats any video, what the research says about screens at every age — and exactly how we design around it.
Read the development guide →Milestones, honestly
The CDC/AAP 2022 checklists and the WHO motor windows, birth to five — why milestones are windows, not deadlines, and when to check in.
Read the milestones guide →The everyday stuff
How much crying is normal, when colic ends, what poop colors mean, spit-up by age, the 100.4°F rule and the newborn weight dip — with sources.
Read the everyday guide →Watch & listen — every video, matched to its research
Each video applies the studies on our science pages — and comes with honest instructions. Sleep long-plays are for ears (dim the screen); sensory videos are for supervised awake moments; learning videos are for ages 2+, watched together. Links open on YouTube.

How we work
- ✓ Evidence-first. Every format decision traces to published research — cited on our science pages, not just claimed.
- ✓ No inflated claims. No video "boosts your baby's brain." We say what our content is for and what it isn't.
- ✓ Audio-first sleep. The sound does the work; visuals stay dark and still, and we ask you to dim the screen.
- ✓ Screen-light by design. Printables for babies' awake time; short, slow videos only for ages 2+.
- ✓ Quiet by design. Our audio is mastered gentle — and every description repeats the safe-volume guidance.
- ✓ No flashing, ever. Every video passes an automated photosensitivity check before upload.
- ✓ Private. This site has no ads, no trackers, no cookies, and downloads need no signup. Our host (AWS CloudFront) keeps standard server logs for 90 days, which we only ever read as aggregate page counts — nothing runs in your browser.
