Catnap
Patterns & Cycles
A catnap is a short nap of around 30 to 45 minutes, usually a single sleep cycle. It's incredibly common and often not a problem at all in young babies.
Catnaps happen when a baby wakes at the end of one cycle and can't yet bridge into the next. Under about five or six months they're completely developmentally normal, so I wouldn't stress. Beyond that, stretching them usually comes back to the wake window before the nap and learning to resettle. Nap three especially can be a bit of a beast, and that's okay.

Circadian Rhythm
Sleep Science
Your baby's circadian rhythm is their internal body clock, the roughly 24-hour rhythm that tells the body when to feel sleepy and when to feel alert. It runs on light, dark and routine.
Cluster Feeding
Feeding & Parenting
Cluster feeding is when your baby wants lots of short feeds close together, often through the evening. It's normal newborn behaviour, not a sign your supply is low.
Contact Nap
Feeding & Parenting
A contact nap is a nap your baby takes while held by you, rather than in a cot or pram. It's a normal and often necessary part of the newborn months.
Early on, contact naps are a tool, not a bad habit, and they can be lovely for both of you. They tend to be longer and calmer because your baby feels safe and warm. If you want to move some naps to the cot later, we do it gradually when your baby is developmentally ready, and you can absolutely keep a contact nap or two up your sleeve.

Controlled Comforting
Methods & Techniques
Controlled comforting is settling your baby with brief, reassuring check-ins at increasing intervals, rather than staying the whole time or leaving completely. It sits between hands-on and hands-off.
Cry It Out (Extinction)
Methods & Techniques
Cry it out, or full extinction, is an approach where a baby is put down awake and not returned to until morning or the next feed. It's the most hands-off method.
It works quickly for some families, but it's not the only path and it doesn't suit every baby or every parent. There aren't just two options of suffer through it or cry it out. I lean toward gentler, more assisted approaches that still build the same self-settling skill, and the right method is the one you can stay consistent with.

Second Night Syndrome
Common Challenges
Second night syndrome is the very common pattern where a newborn who slept a lot on day one wakes and feeds almost constantly on the second night. It's normal and short-lived.
Self-Settling
Methods & Techniques
Self-settling is your baby's ability to fall asleep, and fall back to sleep, without being fed, rocked or held over. It's a learned skill, not a personality trait.
A baby who can self-settle still wakes between cycles, they just put themselves back over without calling for you. It's the single biggest lever for longer naps and fewer night wakes. My mantra when we work together is assisted days, independent nights, and it can be taught gently and at a pace that suits your family.

Separation Anxiety
Common Challenges
Separation anxiety is the stage where your baby gets upset being apart from you, including at sleep time. It's a healthy sign of attachment, not a step backwards.
It often shows up around 8 months and again near 18 months, and it can briefly wobble sleep that was going beautifully. Extra reassurance, a consistent calm goodnight and a predictable routine all help your baby feel secure. A gentle, gradual approach tends to suit this stage best.

Sleep Association
Common Challenges
A sleep association is whatever your baby links with falling asleep and then needs again to get back to sleep. Some help you, some make work at every single wake.
Positive ones like a dark room, a sleeping bag or white noise are easy to recreate and stay put all night. The ones that need you, like feeding, rocking or holding to sleep, have to be repeated at the end of every cycle. Shifting those is usually the key to longer stretches, and I wouldn't call it a bad habit, just a pattern we can change.

Sleep Cycle
Sleep Science
A sleep cycle is one full pass through light sleep, deep sleep and dream (REM) sleep before the brain briefly surfaces again. In babies a cycle runs around 40 to 50 minutes.
At the end of every cycle we all have a little wake, adults included. We roll over, have a sip of water, get comfy and drift back without really remembering it. A baby who hasn't yet learned to link cycles wakes fully at that point and looks for whatever got them to sleep in the first place. That's behind a lot of short naps and frequent night waking, and it's very normal.

Sleep Onset
Sleep Science
Sleep onset is the moment your baby moves from awake to asleep, and the way they get there. Whatever is in place at the start, they tend to want again at the next wake.
If a baby falls asleep on the breast or being rocked, their brain logs that as how sleep happens. So when they surface between cycles, they go looking for the same thing to get back over. Changing what happens at sleep onset is the heart of nearly all the settling work I do, and it's why I start at bedtime first.

Sleep Pressure
Sleep Science
Sleep pressure is the natural build-up of tiredness the longer your baby is awake. Enough of it makes falling asleep easy, too little turns it into a battle.
It works hand in hand with the body clock. If a nap runs long or a wake window is too short, not enough pressure has built and settling drags on. Push the window too far and they tip over into overtired. Balancing wake windows is really just managing this pressure, and it's why I say sleep promotes sleep.

Sleep Regression
Common Challenges
A sleep regression is a temporary stretch where a settled sleeper starts waking more, fighting naps or settling poorly, usually around a developmental leap. It passes.
The common points land around 4 months, 8 to 10 months, 12 months and 18 months, lining up with big changes in the brain, movement or separation awareness. The 4 month one is different, it's a permanent change in how sleep is structured, so it's really a progression. I like to rebrand it as the perfect moment to build better sleep, because once those new cycles arrive your baby can learn to link them. Hold your routine steady and there's so much opportunity here.

Split Night
Patterns & Cycles
A split night is when your baby wakes in the small hours and stays happily awake for one to two hours before going back to sleep. They're not upset, just wide awake.
Nine times out of ten this is a sign of too much sleep across the 24 hours, often a bedtime that's too early or a day nap running long. The fix is rarely the night itself, it's gently trimming total sleep so the night-time pressure stays high. It feels counterintuitive, I know, but it works.

Swaddling
Feeding & Parenting
Swaddling is wrapping a newborn snugly in a light cloth to settle the startle reflex and help them feel secure. Done safely it can calm a young baby and lengthen sleep.
A safe swaddle is firm across the chest and loose around the hips, in breathable fabric, with baby always on their back. The moment they show any sign of rolling, the swaddle goes and you move to a sleeping bag with arms free. Follow Red Nose safe sleep guidance, and if you're in Australia I do love a Bonds Wondersuit underneath.
