Our review
This book moves through a baby's first year using just a handful of words per spread. It covers the major milestones—bump, wait, arrive, crawl, walk—in a way that makes sense for a very young child.
Because it moves so quickly, a toddler can digest the entire arc of a new baby in about a minute. It’s a brief, manageable way to talk about what's coming.

Questions parents ask
How long does it take to read Little Miss, Big Sis aloud?
About 3 minutes at an unhurried pace, including a standard allowance for page turns, pictures and participation, from a word count of 135. Stopping for a longer conversation on every page will add more time.
What age is Little Miss, Big Sis actually for?
Ages 2-4 in our testing, which is narrower than the publisher's range. With 1 sentence a page and vocabulary at 2 out of 5, it asks for that much attention span and no more.
Does Little Miss, Big Sis survive being read on repeat?
Yes, reasonably. It stays bearable through the repeat-request phase without becoming a favourite forever.
Is Little Miss, Big Sis a good book for a child who will not sit still?
It helps that it rhymes. Those three features are what keep a wriggling toddler listening, far more than the subject matter does.
Can a beginning reader read Little Miss, Big Sis on their own?
It is closer than most picture books. With 1 sentence a page and plain vocabulary (2 out of 5), a confident early reader can attempt it, though it is written to be read aloud first.
What themes does Little Miss, Big Sis cover?
We tag it with babies, siblings, first year and family. Those are the threads that actually run through the book, not just the ones on the cover, which is how it earns its place on our themed lists rather than a keyword match.
