Myself my husband and our four kids 10-5 are all vegan. My husband and I have been together for 20 years and have been vegan for 26 and 22 years. Our opinion is that it isn't a decision for everybody however that being said its the decision for us and our kids unless they decide to make the switch. We have hosted Christmas for the past 9 years, we make everything vegan and someone brings a joint of meat and cooks it for the people who want it. However this year my sister in law is attending for the first time ever. She's asked to make her own potatoes, veg and gravy- however there isn't the capacity and there is no need. I have said she can eat non-vegan but I see no reason to cook 2 of numerous things, especially given it is in my house. Finally she is quite outspoken against having vegan kids - and has said she wants them to try bacon on Christmas morning, what is the best way to address this and is this unreasonable? She's staying for a week and I can now only see tension.
