demand request politely that PIL don't buy the children ENORMOUS bags of tat gifts. DD (4) ended up in this horrid frenzy of ripping off paper, discarding gift and grabbing next one, eventually asked to go upstairs and look at their collection of children's books that are always there, ignoring all the new things. DS (2) only wanted to play with one gift and wasn't bothered by all the stuff. I found it stressful as some of it is massive and we have limited space, and the kid's reactions kind of took some of the joy out of proceedings.
Less is more!!
Use the bargain threads again. They were FABULOUS.
Make sure DCs know some gifts are from us instead of allowing everything from us to be from Santa.
Keep organised, this year I was done shopping really early and wrapped a week before, brilliant!
