I'm 'a big card person, I love cards and have a big box saved of all important cards that I've received in my lifetime.
Oddly enough, I don't buy cards for my kids. I kinda forgot/ran out of the time for their first then didn't buy the subsequent years. I stood in the card aisle yesterday for DD1's 4th birthday and didn't really see anything I loved that just screamed her.
I want to start and I hope she doesn't wonder why there are no cards for years 1-3!
