I have a big family and big in-law family also. We have picked names for each kid so I only buy for 2 kids since I only have 2 kids. Each child gets paired up with another similar aged/gender child, so it's easier to buy for that child. We do this on both sides of my family. That way, I'm not buying for anyone who has 5 kids and I'm only buying for the amount of kids I actually have. So, my kids only get 1 gift each from their cousins on my husbands side and one gift each from the cousins on my side. Makes for a much more managable Christmas financially for me anyway.
Then for the sisters/brothers and adults, we do a Chinese gift exchange. Each adult sibling/parent brings 1 gift wrapped with no name tag within the price range of say $10-20.
