I have heard of mom's writing their child a letter that they save & give to them when they are 21! You let one person know about the letter so that in case something happens to you the child will still get it. You right to them about what you want them to know about life when they turn 21! I think it's a great idea, but if your not a keepsake person, may not be right for you.
I also think that ranger rick's animal baby magazine is great for little kids when they are younger. It can be found on the National wildlife website and is very reasonable!
Good luck with finding the right gift for you! - C.!
