Before the move: tell them properly
Children process a move through certainty, not surprises. Show them the new house (photos work if visits can't), let them 'choose' their room even if there's only one candidate, and involve them in packing their own things into two or three boxes they decorate themselves. Ownership beats anxiety.
The kids' essentials box
Each child gets one box or backpack that never goes in the van: favourite toy, blanket, pyjamas, snacks, tablet and charger, and whatever object makes bedtime work. Moving day runs on this box. So does the first night.
On the day: out of the flight path
Loading day with toddlers underfoot is stressful and unsafe. If grandparents or friends can host for the loading hours, take the offer. Older kids can be given real jobs — checking empty cupboards, carrying the plants — because being useful beats being bored.
Feed everyone before the food is packed. The traditional first-night dinner in a new house is a takeaway on a box lid, and honestly, we recommend keeping the tradition.
First night: their room first
Unpack the children's room before your own — beds built, curtains up, the familiar duvet cover on. A child who goes to sleep in a room that already smells like theirs wakes up at home. Everything else can wait a day.
