Your week by week baby guide

Everything you need.
When you need it.

The honest, practical guide a friend writes for you — if that friend had done all the research, made all the mistakes, and put it all in one place so you don't have to.

  • Everything in one place — no more browser tabs and contradictory Google results
  • Every buy list item explained — what it is, why you need it, when, and which brand
  • Appointments, scans and vaccines in order — tick them off as you go
  • Less anxiety — because most overwhelm is not knowing what's coming

sound familiar?

It doesn't have to be this way.

Most first-time parents piece together their knowledge from dozens of sources — and still feel underprepared.

the spiral

One question leads to 14 tabs, contradictory answers, and more anxiety than you started with. At midnight.

the list

Every list tells you what to get. None tell you what it's for, when you need it, or what to skip.

the overwhelm

Not knowing what you don't know yet is the worst feeling. Most anxiety comes from not having a clear picture.

What's inside

Four things that make it different

Not just a list. Not just a calendar. All four things together, in the right order.

Buy lists

Not just "buy a swaddle"

Every item explained — what it actually is, why you need it, which brand we'd recommend, what you can get second-hand, and exactly when you need it so you're not buying everything at once.

"Love how this not only tells me what I need but why, and when. Such a time saver!"

Weaning

A proper weaning checklist

First foods in the right order — iron first, then allergens one at a time, then variety. All 14 allergens flagged with timing. What not to give before 12 months and why.

What nobody tells you

Once introduced, allergens need to stay in the diet weekly. Occasional exposure isn't enough — the guide flags this clearly so you don't undo your work.

Guidance

The honest answers to the 2am questions

Temperature

Baby's hands will always feel cold

Check the back of their neck instead. The guide explains how to dress baby for the room temperature — with a full TOG chart.

all in the guide
Sleep

The 4-month sleep regression

It's not a regression — it's a permanent change. The guide explains what's happening and your options, before it hits.

Feeding

Winding takes 20 minutes in week one

All three positions, and the honest truth: it gets much faster by month three. Put a film on.

Development

Tips, not just milestones

Not just what your baby can do — specific things you can do to support development at each stage.
