L.G.
I made a time capsule for each of my kids on their first birthday. I asked guests to write a note of blessing to them and put it in a sealed envelope to add to the time capsule. I plan to save it until they are older... graduate, married, first child, not sure exactly. They are still in the top of my closet. My kids are 7 & 8 now and I look forward to passing it on to them.
Good luck! L.
