40 weeks.
Every single one.

What's happening to your baby, what's happening to your body, what you might be feeling — and what to do about it. Written for real humans, not medical textbooks.

You & your partner

Most pregnancy guides tell you what's happening to the baby.
We also tell you what's happening to you.

There is a version of pregnancy information that reads like a textbook — clinical, detached, focused almost entirely on foetal development while treating the person doing the growing as an afterthought. This is not that. Every week here covers your body, your emotions, your partner's experience, and one specific thing to focus on. Because pregnancy is not something that happens to a foetus. It happens to a whole person.

💙
Your feelings, not just your symptoms
Every week includes the emotional reality — the anxiety, the wonder, the ambivalence, the grief alongside the joy. The things other guides skip.
👫
Your partner, included
Every week has a partner section — what they might be experiencing, what they can actually do, and how to navigate the weeks together rather than in parallel.
One thing to do this week
Not a list of fifty things. One specific, actionable thing — whether that's a question to ask your midwife, something to read, or something to do together.
