The world has sensations now. Why your newborn suddenly seems unsettled (and what’s actually happening in their brain) Around week 5 (based on your baby’s due date ), your baby enters Leap 1 aka the leap of sensations . If birth was the moment they entered the world, this leap is when they start to notice it . Light, sound, touch, movement, temperature - everything feels dialled up. They might cling more, cry more, or need extra help falling asleep too. You're not doing any

The world has perspectives now. Why your toddler suddenly argues with reality (and why sleep can wobble again) Around week 59 (based on your toddler’s due date), they enter Leap 9 - the leap of principles . If Leap 8 was about understanding how routines and sequences work, Leap 9 is about understanding that other people have their own thoughts, intentions, and points of view . Which is a huge deal. And yes, sleep can take a hit again, because big brain upgrades rarely arriv

The world has an order now. Why your baby suddenly anticipates what’s coming next (and why sleep can wobble again) Around week 41 (based on your baby’s due date) , many babies enter Wonder Weeks Leap 7 , the leap of sequences . If earlier leaps were about noticing the world, this one is about understanding what comes next . Your baby isn’t just reacting anymore. They’re predicting. And yes, sleep can feel a little off while their brain gets busy connecting the dots. The scien

The world has rules now. Why your toddler suddenly says “No!” to everything (and what’s behind the bedtime chaos) Around week 55 (based on your baby’s due date), your toddler enters Leap 8; the leap of programs . If Leap 4 felt like the world turned on , this one feels like the world now has a manual , and your toddler just found the table of contents. They’re testing, pushing, experimenting… and no, you’re not imagining it - sleep often takes a hit (like in any Leap) The sc

YOU MADE IT!! The end of the Leaps - and the start of a new kind of parenting. The final leap, and it’s a crescendo Somewhere between around 70 weeks post due date (around 18 months old give or take for this one), your child enters Leap 10 , the final Wonder Weeks leap. But before you cue the celebratory music, let’s talk honestly: this one’s not necessarily a walk in the park (were any?!) It’s intense. Emotional. And full of push-pull behaviour that can leave even the most p

Welcome to the world of categories Why your baby suddenly wants the red cup, not any cup and how their brain is levelling up again. Around week 37 (based on due dat e, not birth date), your baby enters Wonder Weeks Leap 6 and life gets a bit more specific. Suddenly, they’re sorting, comparing, and demanding the exact toy, snack, or spoon they had in mind. And when they don’t get it? Cue the frustration. This leap is all about understanding categories and it’s one of the r

Leap 4 - The world turns on. Why Leap 4 is the “big one” and how to survive the sleep shake-up Around week 19, give or take (based on your baby’s due date), your baby enters Leap 4 , which is a developmental explosion so big it’s often mistaken for something being wrong . They were sleeping better, now they’re up all night. They were settled, now they’re cranky. It’s one of the most dramatic leaps in the first year, and one of the hardest for parents. The science: What’s chan

Welcome to the World of Patterns Why your baby suddenly seems fussier, hungrier, clingier, and what’s really going on in their brain. Around week 8 , give or take (always based on due date , not birth date), your baby enters Leap 2 , and life can get… spicy. Babies who were once calm may now be unsettled, wake more often, crave contact, and cluster feed like they’re training for a sport. It’s not “colic.” It’s not anything you did. It ’s their brain levelling up. So let’s bre
