DH and I don't want to invite PIL over on Christmas day. We don't get to spend enough time with our children and just fancy a year when it is just the 5 of us. If other people are there the dynamics change and I would prefer playing with the kids and their new toys than catering for another 2 people. Is it ok to put ourselves first? Likely in years to come as PIL age we will end up 'looking after' them on Christmas Day so while they are healthy and mobile I want to relax my way.
