most people I have something for - a couple of things I've made, things I found cheaply etc.
Giving eggs would be a great idea except I'm not posting them - the way our postal service has been they'd take a month to get there! (I'm in the UK, we've had postal strikes this year...)
I bought a fleece dog blanket from the £1 shop and made 3 gifts out of that...  so this year it's more token gifts than "here, have a sackload of presents!" which is what I've been doing for previous years.  
the "only buy for the children" thing is what my father's family did (he was one of 8, and they ALL had children) - but even though my parents bought for all my cousins for years while they had no children, as soon as my older brother was born the rest of the family decided that there were just too many children and that they weren't bothering any more.
