We spent today with my MIL, BIL and his wife & son, and my kids - 9 people across 3 households in total. It was a little smaller group than usual - partly because of covid, partly because two of my 'bonus' kids have new SOs they wanted to spend the holidays with - but otherwise fairly normal. My mom opted not to come because she was having a bad/no driving day (one of her meds causes dizziness/vertigo, so she never knows what she'll feel up to from day to day) but my girls are going to tag along to see her when I do her shopping next week and we'll have a mini-Christmas celebration then.
Tomorrow is just our family in our house, but other than my mom not being here to stay tonight, that's how we always do Christmas Day.
