What to do with your grown kids' stuff when you downsize

Somewhere in your house there is a bedroom that still belongs to an adult who lives elsewhere. Trophies, yearbooks, a bass guitar, boxes that were “just for a few months” several years ago.

It is tempting to sort it yourself, either by keeping all of it out of love or by quietly throwing it out. Both go badly. You cannot know which of those objects matter, and guessing wrong in either direction costs you space or costs you an argument.

The better approach is simple: it is their stuff, so it is their decision, and your job is to give them a clear deadline and make the decision easy.

Tell them early, and in writing

As soon as you are seriously planning to move, tell each child what is happening and what you need from them. Do it in a message they can reread, not only in a phone call.

A message that works has four parts: what is happening, what you need, by when, and what happens after that date.

We are planning to move to a smaller place next spring, and we won’t have room to store your things. Everything of yours is in your old room and in the labeled boxes in the garage. Please go through it by March 1. You can take it, ask us to ship what you want, or tell us to donate it. Anything still here after March 1 we will donate or discard. We’d love to do it together if you can come for a weekend.

Adjust the tone to your family. Keep the date.

Make it easy to decide from a distance

Children who live far away often put it off because the task feels shapeless. Shrink it for them.

• Gather everything in one place. One room or one stack of boxes per child, so the amount is visible.
• Send photographs. Open each box, lay out the contents and take a few pictures. Many decisions can be made in a ten-minute video call.
• Offer three choices, not an open question. Take it, ship it, or let it go. “What do you want me to do with all this?” gets no answer. “Trophies: ship or donate?” gets one.
• Agree who pays for shipping. Say so up front. A box of keepsakes costs far less to send than a dresser, and they should know that before they ask for it.

Give a real deadline

Set the date well ahead of your move, not the week before. Two to three months of notice is fair, with a date that still leaves you time to clear what remains.

Send one reminder a month before and one a week before. Then follow through. A deadline that slides teaches everyone that the next one will slide too, and you will end up packing their boxes into your new, smaller home.

What about the things they say to keep “for now”?

“Can you just hold on to it?” is the most common reply, and it is a request for free storage with no end date.

You can say yes to a limited amount. Offer one container per child that comes with you to the new place, and let them choose what goes in it. Anything beyond that, they store themselves. If they want to rent a storage unit, that is their choice and their bill.

Things worth keeping yourself

Some of what is in those rooms is yours, not theirs: the drawings they made for you, the cards, the outfit they came home from the hospital in. Sort those as your own keepsakes, on your own schedule, and keep the ones you love. They belong with the photographs and letters you will leave until last.

It can help to photograph the rest. A picture of the science fair project does the same work as the project, and fits in a much smaller house.

If they do not respond

Sometimes the deadline passes in silence. Before you donate anything, send one last short message naming the date and what will happen. Then set aside the few things that are clearly irreplaceable, such as photographs, letters and documents like diplomas, and let the rest go as you said you would. If something looks valuable, such as jewelry, an instrument or a collection, keep it aside and get a clear answer in writing before it leaves the house.

You gave fair notice. Carrying their belongings into your next home is not a kindness to either of you.
