When packing for your family do you tend to put all of your kid's clothes with your clothes in a big duffel back or do you find it easier to pack everyone's clothes in a separate bag or backpack? I think it's easier to pack everything together if you have young kids. Until your kids can pack for themselves, this just makes it a lot easier.
We always visit my in-laws for a couple days every holiday. I only have one daughter, she's two. I pack my husband's and my clothes together and my daughter gets her own because we pack WAY more stuff for her than for ourselves.
Whenever we have long trips or travels, this is the setup of our luggages or backpack:One bag or luggage for my husbandOne bag or luggage for me and my sonAnd then with each bag, there are compartments:Clothes for sleeping in like pyjamas, shorts and white shirtsClothes for going out like pants, t-shirts and blousesUndiesA separate plastic for spoiled or worn clothesToiletriesBibs and handkerchiefsTowelThat is how I always pack our bags and luggages. My son is growing very fast though and I think with upcoming trips he might need his own bag. Lol.
