Moving with a baby isn't a harder version of moving. It's a different task altogether, because the baby's routine is the thing most likely to break and the most expensive thing to repair afterward.
We moved from California to Bangkok with a small child and I've done several moves since, so almost everything below comes from getting it wrong at least once. It follows from a single principle: the baby's sleep setup is the last thing packed and the first thing assembled, and everything else in the house is allowed to be chaos.
The easiest age to move
If you have a choice, and very often nobody does, the gentlest window is the first three or four months, when a baby has no attachment to place, no mobility, and a routine flexible enough to survive being ignored for a fortnight. The hardest stretch is roughly eight to eighteen months, when separation anxiety peaks, sleep is fragile, mobility makes an unsecured house dangerous, and the child understands just enough to be unsettled without understanding what's happening or why. Toddlers past two do better than one-year-olds, because they can be told. A simple repeated story (we're going to a new house, your bed is coming with us, we're all going together), plus a visit or some photographs beforehand, does a surprising amount of work. We told ours the same four sentences for three weeks and it helped every one of them.
How to pack it
One box counts for more than all the others put together, and it should be the last thing loaded and the first thing opened. Pack a first-night box, put it in the car and not the van: crib sheets, sleepwear, a familiar sleep item, diapers, wipes, formula or feeding equipment, medication, a change of clothes for everybody, phone chargers, toilet paper, a kettle and some mugs.
Photograph the crib before you take it apart, and keep every fitting in a labeled bag taped to the frame. Reassembling a crib at nine in the evening from memory is the classic moving-day mistake and I've made it.
Pack the nursery last and unpack it first, because everything else can happily stay in boxes for a week. Keep two or three familiar items unwashed, since smell is a strong settling cue and a freshly laundered sleep companion is a different object entirely to a baby.
Label by room and by urgency, and mark the three boxes you need on day one so they don't end up at the back of the van, and please don't buy new furniture, new sleepwear or a new bedtime routine for the new house. Change one thing at a time. The house is already the one thing.
Settling in again
Moving day itself
Ideally the baby is somewhere else entirely. Childcare, a relative, a friend, a day at nursery. Moving day with an infant present is slower, more dangerous and more distressing for everybody than moving day without one, since open doors, stacked boxes, exposed cables, propped furniture and strangers carrying heavy things add up to a hazardous afternoon for a crawling child.
If she must be there, designate one safe room, empty it last, and keep one adult assigned to her and to absolutely nothing else. Keep the day's feeds and naps as close to normal as you can even if it slows the move down, because a missed nap costs far more later than it saves now.
Watch the temperature, since doors propped open on a cold day or a van on a hot afternoon both change conditions faster than you notice. Reinstall the car seat correctly, check it before the last trip, and assemble the crib before you do anything else at the new house. Before the kettle.
Protecting sleep afterward
Expect a regression and plan for it to be temporary. A week or two of worse sleep after a move is completely normal even when you've done everything well, and what shortens it is sameness: the same crib, the same sheets, the same order of events at bedtime, the same words, the same darkness and the same noise level.
Recreate the old room's conditions before you improve on them. Keep the same relative position of crib to door if you can, the same blackout level, the same white noise if you used it. Reintroduce the routine on the very first night however chaotic the house is, because the sequence counts far more than the setting.
Expect more night waking and more resistance at bedtime for a week or two, and hold the routine steady, adding no new interventions on top. Don't use the move as the moment to drop a nap, move to a bed, night wean or change rooms, because every one of those is a separate project. Get the new room properly dark, since unfamiliar streetlights are a common and very easily fixed cause of early waking after a move.
What to baby-proof immediately
A new house is an unproofed house, and a mobile baby will find its worst feature inside an hour. Do the urgent layer on day one and the rest across the following week.
Anchor anything tall to the wall: bookcases, dressers, wardrobes, the television. Furniture tip-over is one of the most serious and most preventable home hazards for toddlers. Put up stair gates before the first night if there are stairs. Ours went up on day three, I think, which was two days later than I'd have liked.
Move the crib away from windows, blind cords and curtains, and deal with looped blind cords on arrival, because they're a strangulation risk. Check the smoke alarms, and if the property has any fuel-burning appliance, check for a carbon monoxide alarm too, since in an unfamiliar house you have no idea what the previous occupants maintained.
Lock away cleaning products, which multiply during a move, and look at whatever was left behind in the cupboards. Then walk the place looking for its specifics: a balcony, a pond, a different type of window, a boiler at child height, a step down into a room.
If the move is international
The administration is the hard part, and it takes a lot longer than the packing. Several of these have lead times measured in weeks, so start early.

Register with a doctor or health service in the new country as early as you can, since in some systems that registration gates everything else.
Check which routine vaccinations differ, as some countries give doses others don't and catch-up schedules are common after a move. Carry medication in its original labeled packaging with a prescription or a letter, and check whether anything you use is restricted at your destination. Keep passports, birth certificates and residency documents in your hand luggage and never in the shipping container.
Assume the shipping will be slow, six to twelve weeks is realistic, and buy or borrow a safe sleep space for the interim. Please don't improvise one. Check that any car seat you already own is legal where you're going, because standards aren't interchangeable between regions and an unapproved seat may be both unlawful and uninsured.
Take the climate seriously. Moving between a temperate and a tropical country changes sleepwear, layering and the whole skin routine, and it takes a few weeks to recalibrate. Holly's eczema arrived in our first Bangkok summer and it took me longer than I'd like to admit to connect the two.
And the adults
Moving ranks high on every list of stressful life events, and doing it during the first year compounds the two hardest things at once: disrupted sleep and disrupted support.
The support network is the part people underestimate most. The neighbor who could take the baby for twenty minutes, the group you'd finally found, the person at the clinic who knew you and your history. Rebuilding all of that takes months. Start in the first fortnight, because feeling settled is downstream of it.
Lower the standard for a month, wholeheartedly. The house doesn't need to be finished, the boxes can stay where they are, and the only real deadlines are a safe place for the baby to sleep and a working way to feed her. Everything else on that list is allowed to slide, and I promise you it'll keep.
