Traveling in winter

My siblings were here last weekend, we had our gathering and they were excited for my kids who are up for another trip soon. But my kids love places with snow. The joy of playing in the snow remains until now and they look forward to going to those places again. Whenever we mention we are going places, the first question pops up will be, will there be any snow? I couldn't hold my laugh when they anticipated snow in Taipei. The uncle is going to New Zealand in winter and they are envious of him. Xuan asked him to bring home some snow. Anyhow, even it's not winter in Europe, I'm still cracking my head what to pack for all of us. We are truly minimalist, I do not have to think about dress up at all. It's still chilly and my sis asked me to bring some thermal wear. I'm already determined to not over pack. I think I have to change my plan.
