3:30-4 when we are at home.
Perfect time for us as it means we get a lovely breaksfast (home made bread, smoked salmon and champagne) a leisurely opening of presents and getting dressed up.
Relatives come round at about 12, more present opening and champagne. Children get plenty of time to play with their gifts and I get plenty of time to watch without stressing in the kitchen and then we all sit down to a fab "lunch" at about 3:30
And still early enough to indulge in supper and chocolates in front of the TV later. Perfect.
