We always spend Christmas Day just me, DH and DD. DD is 9y now. Dh and I have always had Christmas Day alone since we moved in together. We see family - who we get on fab with btw - Christmas Eve and Boxing Day but Christmas Day is our day at home, no routine, no demands, no pressures, no nothing.
We get up when DD wakes up, but no going downstairs til after 7, even if she wakes before.
I go down to see if FC has been and grab my camera. Then DH leads DD dowstairs with her eyes shut. FC is always unwrapped waiting first.
Then it is present time. We sit round the tree nd DD takes it in turns to hand us a present each, which we unwrap, look at, etc before the next person's turn. DD always ends up with way more, so once me and Dh have finished we have a little break. DH makes some tea and breakfast and then DD will continue.
Later we will have some fizz and DD will have a drink, etc too. We will then phone family/friends to wish everyone a merry Christmas and to say thanks for gifts.
Then a bit later again we might decide to actually get dressed. We may go for a walk.
We have a late lunch around 3ish. More wine.
Then we will settle down and watch a film or Christmas telly, play a game, watch DD with her gifts, play around with our new gifts. More wine. We might even get back into PJs earlish!
Then later on we might have some dessert, instead of proper food. Probably more wine or something like Baileys.
DD will go to bed around normal time. DH and I will watch some telly/fim and chat. More wine :)
