Write notes back & forth with your child. Leave it on their bed, when they have a chance, they write back and leave it on your bed. How neat would it be to have those notes to look back on? Wish I would have done this!
amazing graduation present for your kids (or nieces/nephews)! Every year write them a letter until they're 18, and put a small amount of money in it, then when they graduate - give them all the letters + money!
