Nobody really warns you about infant sleep. Or maybe they do, and you just don’t really understand them until you’re living it.

Around the time our son hit three months, sleep became the single hardest part of new parenthood — harder than feeding, harder than diapers, harder than all of it. Naps fell apart for no apparent reason. Bedtime drifted all over the place, night to night. And a constant set of questions ran in the background: he’s been awake a while now — is that too long? Too short? Did we miss the window? Is he overtired, or not tired enough?

The apps we tried kept falling short

We did what everyone does — downloaded the popular, well-reviewed sleep apps. They helped for a while. But they let us down in the same ways, over and over.

The schedules were generic. Built for some average baby, not ours. You plug in an age, you get a chart. And when our son didn’t match the chart — which was most days — the app had nothing useful to say. Worse, on an off day the chart could be flatly wrong: a three-month-old never needs a four-hour wake window at 4 p.m.

They never explained themselves. “Next nap at 1:30 PM.” Okay… why? Based on what? When you’re sleep-deprived and second-guessing every decision, “just trust me” isn’t good enough. You want to understand the reasoning — partly so you can learn, and partly so you can tell when the advice doesn’t fit your kid.

So we kept doing the math ourselves

He slept from 9:40 to 11:32, he’s been awake since, it’s almost 1:00 — so when’s the next nap, and how long should it run? Over and over, all day, every day.

What helped us most was leaning on AI. I’d hand it the day’s sleep log, and it could actually read the context of the day — not just the clock — and lay out a sensible plan for the rest of it. It worked, better than I expected. But it was slow and manual: I was copying the log in by hand every time, and even then the AI only ever saw a thin slice of the picture.

Eventually I started building something to do it for us automatically — and to give it the full picture the manual way never had. It started rough, but it worked surprisingly well. And more importantly, it worked for our baby, on our actual day, not some idealized one.

Over several months of hard work, that prototype became Ceddie Sleeps.

What makes Ceddie different

Ceddie is built around three ideas the apps we tried kept missing.

It’s built around your baby, not the average baby. You log naps and night sleep as they happen, and Ceddie builds the day’s schedule around how your child is actually sleeping — their age, their patterns, and what’s already happened today. Not just how long each sleep was, but the full context of the day.

It bends with the real day. Babies don’t read schedules. A short nap, an early wake, a long settle, a rough night — Ceddie reworks the rest of the day around what actually happened, instead of holding you to a plan that stopped making sense hours ago.

It always explains itself. This is the part we’re proudest of. Every schedule comes with a plain-language note on the reasoning — why this nap will likely run short, why bedtime lands where it does, what to watch for. You’re never just handed an instruction. You come away understanding a little more about your own baby’s sleep, which is the thing that actually helps over time.

Built by parents, used by parents

We’re not sleep experts, and Ceddie isn’t a doctor. It’s a tool we built as parents, for parents — and we use it every single day with our own son. It’s been our daily driver for several months now, and honestly, using it ourselves is what made it good. Every rough edge got found because one of us hit it.

A handful of other families have started using Ceddie with their own babies now — and it’s helping them too.

We’d also rather show you nothing than show you a bad schedule. When there isn’t enough information to give you something genuinely useful, Ceddie says so instead of guessing. No schedule beats a bad schedule — every time.

Come try it

Infant sleep is hard. It might be the hardest part of the early months. We built Ceddie because we needed it ourselves — and if you’re in the thick of it too, we’d love for you to try it and tell us what you think.
