My lot always open their stockings when they wake up. Get dressed and go downstairs. They open their 'little presents' (from us) then they have breakfast. Then they open their 'main presents' (from us) Then they have the rest of the time to play while I do dinner etc. After lunch, they open their presents from the rest of our family. Then in the evening, when they are in their PJs, my dcs exchange their gifts between themselves, which they love, and open any cards that have got money in (i put them on the tree the night before if i know they have got money/vouchers in) and one last present from us that we save to open, usually just a little something, pencils or book or something. Then after the dcs have gone to bed, dh and I open our presents and exchange our gifts between us.
I remember when i was younger it was just a case of get up and unwrap all the presents all in one go. I like spacing it out for my lot! Something to look forward
