About Hello Little One
An independent guide for expectant and first-time parents in the UK, built around a short daily email that follows your pregnancy day by day.
Who's behind it
I'm Theo, and I started Hello Little One when my partner was pregnant with our first child.
What struck me most was how much information there was. Books, apps, leaflets, forums, and advice from everyone we knew. Nearly all of it was well meant and most of it was useful, but it was hard to know what mattered this week and what could wait. What helped most was a small dose each day: a short read about what was happening right now, so I could support my partner and knew what to focus on.
What you'll find here
- A daily email
- Every morning, a short note about the exact day you're on, from the first day of your last period, through all 280 days of pregnancy, to six weeks after the birth.
- Pregnancy day by day
- The same content on the website, one page per day, with the NHS appointments and checks marked along the way.
- Guides and reviews
- Practical guides to the UK side of pregnancy, and honest reviews of the things you might buy. When we earn from a link, we say so.
- Written for the UK
- NHS appointments, UK screening and maternity pay, and British spelling throughout.
How we write and check our content
- We start with the official guidance. Health information follows the NHS, and money and rights follow GOV.UK. Every guide lists its sources at the bottom, so you can check them yourself.
- We keep it up to date. Each guide shows when it was last updated. Anything with rates or allowances, like maternity pay, is checked every April when they change.
- We say where our advice comes from. When something is our own experience as parents, we say so. When a page has been checked by a qualified professional, it says so at the top.
- We're open about money. Some buying guides include affiliate links, which are always labelled. They never decide what we recommend. How we make money.
- We fix mistakes. If you spot something wrong or out of date, email hello@hello-little-one.com and we'll correct it.

What's new
May 2026
Full pregnancy content rewrite
All 280 pregnancy days were rewritten. Week references are accurate to the exact day, baby sizes follow a consistent growth curve, and week numbering has been checked across every day. Postnatal content (days 281 to 322) is unchanged.
May 2026
Week and day counter corrected
The week and day counter in every email now shows "1 week and 0 days" on day 7, "2 weeks and 0 days" on day 14, and so on. Before, the week count was one higher than it should have been.
May 2026
Postnatal emails
The emails now carry on for 42 days after your due date, covering the first six weeks: recovery, feeding, the 6 to 8 week check, development, immunisations and postnatal mental health.
May 2026
Early arrivals
If your baby arrives before your due date, you can update the birth date and your emails switch straight to postnatal content. Update your birth date.
May 2026
Security improvements
Rate limiting on all public endpoints, rotated API keys, and HTTPS for all traffic.
