We are hosting Christmas for the first time this year. Just us (family of 5, small child, toddler and newborn), our parents, siblings and their kids. However both our families are big and everyone has said they're coming.
This means we've got 18 adults, 10 children and 4 babies 
For context we are all really close, and our families are all friends so that's not an issue. Also everyone will bring a dish so I won't be the only one cooking. I'm worried about how we will accommodate everyone and it not feel like chaos though.
I was planning on having them all come over at 2.30pm. Any tips on how to organise the day? I'm being massively thrown in the deep end here so need some advice from seasoned professionals!
- Our house isn't huge but it isn't small either. Our kitchen table can sit 10 people at a squeeze.
- We have a decent sized playroom for the kids with a big TV in it.
- Living room sofas and chairs can probably sit 10 people.
