I have kept stuff the kids have made me over the years, self made mothers day cards from when they were little, i even put a christmas decoration they made on the tree and the youngest is 18! I have kept a love letter given to my daughter when she was about 8 from a neighbour, bless him its so sweet put his heart and soul into it haha, and a lovely letter from my son aged 6 after i made him try broccoli, says, dear miss pig, don't ever give me that again i hate it, love from Nathan hahaha!! Not loads of stuff just in a couple of boxes in the loft :-)
