About First52

First52 is built by a new dad, during his son's first year, one week at a time.

When his son was born, he did what every new parent does at 3 AM: searched the internet one-handed, half asleep, and found answers written for "0–3 months" — as if week 2 and week 11 were the same baby. They are not. So he started keeping the notes he wished he'd found: what this week actually looked like, how long the baby could really stay awake, what was normal, what wasn't, and what was about to change.

Those notes became First52. The week pages are written as the weeks happen — the guide is growing up alongside the baby it describes, and it will be complete at the first birthday.

How the information is put together

Every page starts from published guidance: sleep durations from the AASM consensus endorsed by the American Academy of Pediatrics and the National Sleep Foundation, developmental milestones from the CDC checklists. Wake windows reflect the ranges pediatric sleep consultants commonly work with. The lived week then checks those ranges against reality — where the week and the chart disagree, the page says so rather than smoothing it over.

What First52 is not

It is not medical advice, a sleep-training program, or a substitute for your pediatrician. It sells nothing in its first version, runs no advertising, and tracks no one. It is one family's first year, organized so it might make your family's first year a little less mysterious.

Educational information only — not medical advice. If you have any concern about your baby's sleep, feeding, or development, talk to your pediatrician.
