Sleep regression explained by age, from 4 months to 2 years, with ten calming wind-down activities and scripts. Not medical advice, free to try today.
On a laptop?
A sleep regression can’t really be fixed, but a calmer wind-down makes it much easier to ride out. When a baby or toddler who was sleeping fine suddenly wakes repeatedly, fights bedtime, or drops naps overnight, it usually settles again within a few weeks as their brain and body catch up with whatever leap is going on.
Below is a look at the common ages sleep regressions turn up, followed by ten activities from the Mooshie Moments app for children aged 1 to 4, covering daytime play and a calmer bedtime routine. Each uses things you already have at home and comes with the exact words to say. Mooshie’s activities start from 6 months, so for the younger regressions below, the wind-down ideas rather than the app itself are what applies.
Sleep regressions tend to cluster around certain ages, though every baby’s timing is different and not every child has a rough patch at each one.
Sleep cycles change to a more adult pattern, with lighter sleep between cycles, which often means more waking. This one tends to hit hardest because it’s usually the first.
Object permanence and separation anxiety are developing together, so babies wake and want reassurance you’re still there. Crawling or pulling to stand often lands around here too, and babies sometimes practise the new skill in their sleep.
Walking and a wave of new language often coincide with disturbed nights, as a busy brain processes the day.
A nap transition, often dropping from two naps to one, can throw bedtime and night waking off for a few weeks.
Imagination is taking off, which is wonderful in the day and occasionally unsettling at night, alongside a growing sense of independence that can turn into bedtime stalling.
These are general patterns, not guarantees, and there’s rarely one single cause. If sleep has changed suddenly and stays badly disrupted for more than a few weeks, or you’re worried about anything else going on, it’s worth mentioning to your health visitor. For babies, keep following safe sleep guidance throughout, such as the advice from the Lullaby Trust, on a firm flat mattress, on their back, in a clear cot.
What happens in the day affects the night. A little independence practice and a body that feels settled both help, without any pressure at bedtime itself.
Turn “staying in bed” into a light daytime game with a timer, so the skill is already familiar before it’s needed for real at night.
You’ll need: their bed
If a bed change is part of what’s unsettled things, let your toddler choose their own bedding and properly explore the new bed in daylight, well before bedtime.
You’ll need: their new bed, bedding they’ve chosen
Sit close at bedtime to start with, then move your chair back by a few feet every few nights, so your toddler discovers gradually that they can settle with you a little further away.
You’ll need: a chair
Whatever’s driving the regression, a predictable run-up to bed, same steps, same order, gives an unsettled body something steady to lean on.
A quick toilet visit slotted in after dinner, before pyjamas, is a small practical habit that can reduce night wake-ups.
You’ll need: nothing
The same song, and the same little kiss on the same spot, every single night, becomes a bridge that tells the body it’s time to rest, even on a rough week.
You’ll need: nothing
If your presence at bedtime has become part of the routine, shrink it gradually over a few weeks rather than all at once: chair by the bed, then the foot of the bed, then the door.
You’ll need: a chair
Standing tall as a “snowman” and melting slowly, one body part at a time, is a physical way to ask a wound-up body to release tension before lights out.
You’ll need: a rug or the bed
Rolling your child up snugly in a flat blanket, arms tucked in, gives even pressure across the body, which many children find calming before sleep.
You’ll need: one light blanket
If the dark itself is part of the worry, a hand shadow that gets sleepy and lies down turns the wall into something your child controls, rather than something to fear.
You’ll need: a small torch
Let your child “order” tonight’s dream the way you’d order food, writing it down and sliding the ticket under the pillow, which gives an active mind something pleasant to settle on.
You’ll need: a scrap of paper, a pencil
Plus one picked for your child every day, matched to their age and how today is going.
“I used to spend 30 minutes looking for an activity on Pinterest, get overwhelmed, and just turn on the TV. Mooshie takes 5 seconds.”
“Finally, an app that tells me to put my phone away. The activities are actually doable with stuff I have in my junk drawer.”
“As a pediatric OT, I love that these activities build core developmental skills without feeling like ‘homework’ for parents.”
Sleep regression is one of Mooshie’s built-in topics, alongside meltdown recovery and separation anxiety, so there’s somewhere specific to turn on a hard week. Activities in the app start from 6 months, so the ideas above cover the earlier ages where the app itself doesn’t yet apply.
Nothing in the app is for your child to watch or tap. Have a quick look, then leave the phone in another room.
Most sleep regressions ease within two to six weeks as your child’s brain and body adjust to whatever developmental leap is underway. Keeping the routine steady through it tends to shorten the rough patch.
Around this age, many babies are developing object permanence and separation anxiety together, and often practising crawling or pulling to stand, all of which can disturb sleep for a while.
It’s often linked to a mix of things at this age, including a leap in imagination, growing independence, and sometimes a nap transition, rather than one single cause. It tends to settle as the new skills bed in.
Generally no. Keeping the routine as consistent as possible, rather than introducing new steps, new pyjamas or a different bedroom, usually helps more than changing things up.
If disrupted sleep continues for more than a few weeks, seems linked to pain or illness, or you’re worried for any other reason, speak to your health visitor or GP. Always follow safe sleep guidance for babies, such as sleeping on their back on a firm, clear mattress.
