K.S.
We just moved in August. The biggest mistake we made was not starting with the packing and purging process soon enough. We kept putting it off and then ended up just throwing stuff into boxes to have it ready for the truck (we just had family and friends helping us move). The most frustrating part is that we are throwing away a lot of stuff NOW. During these cold winter months we are going through all of the misc. boxes in the basement and realizing all of the junk that we spent effort on bringing from one house to the other. We did take quite a bit of stuff to the local Goodwill (furniture, clothes, toys, etc.) before we moved; which is also nice for tax write offs, but we found it was nowhere near enough.
A few helpful tips:
1. start gathering boxes now
2. start packing anything you don't use regularly, now
3. label each and every box with what is inside and what room you want it in
4. go through your clothes and your children's clothes and take anything you won't wear again to Goodwill (or Salvation Army or whatever). Same for toys, books, furniture, accessories, etc. Ask your kids to help decide what toys they can give to needy kids.
5. keep important papers/information in one spot and ensure that you keep that with you during the moving process so that you can always find it
6. look for daycare and school information now
7. if you are not familiar with the area get a map, look on the web, figure out if your fave chain restaurants deliver, etc.
Good luck to you with your move!
