We're going on a 3-week family vacation to France next week and I'm starting to put together our packing lists. My husband and I are generally light packers and we try to fit everything into a backpack along with a couple of daypacks when we travelled in the past... But I don't know how much clothing to bring for my 10 month old! Any suggestions?

The temperature will vary between 10 to 25 degrees Celcius.
