If deciding who to give the items to is difficult, do games with prizes, or raffles. Whatever is left can be donated to Goodwill. If you are moving far away, make it two or more days of festivities. It will be great to spend time with loved ones(and get any help you can packing) if you are attempting to do-it-yourself.
The interactions with close friends & family will ease the stress of the move off your kids as well. We must keep in mind these little people are thinking about school & friends, and may need help adjusting. We are in the social media era of living on our phones & laptops. They still need friendships, connections, attention & love(in person).
Also remember to get a lot of rest the night before. When you hire movers, it's like starting a new bank account. You are taking your life, memories, & future, & trusting it with a company you may or may not be familiar with. That very reason is why we take extra steps to keep you comfortable throughout the day. In the end you are paying the bill, so let the movers do the work. You will be glad you did in the end.
I hope this has inspired a party, or just a day with your family. Keep reading, & Happy Moving!!!
