It can be very stressful simply to witness a family trying to move house never mind actually being the family involved. Speaking as someone who has experienced this many times, from bth sides, I can tell you moving is so much easier when the home is uncluttered and organised. It becomes apparent to most people when moving house how much stuff they have that they really don’t need or use, but now have to find the energy to prepare it, the means by which to move it and the space to accommodate it in the next home. This, I can tell you, is rarely a simple task especially given all the variables of each family’s circumstances. Such as…
1. Small children to deal with during the move, especially babies.
2. Moving nearby. Which means moving all your belongings from one place to another and having to deal with cleaning up your previous residence while trying to get organise in the new one that you’re moving into.
3. Trying to fit all the work in between work and family commitments.
4. Health issues to contend with.
… and the list goes on.

So,if you live in a a situation that isn’t particularly permanent, the time to consider how much excess stuff you have around your home is now. Not when when a move is imminent and there is little time left to reduce and prepare.
