I told my mom by getting a sign made that can hang like a picture on the wall that said, "The only thing better than having you for a mom is my child having you for a grandma." I wrapped it up and she opened it but you could send in a package.
Send her a candy necklase spelling out grandma on it
No I don't sadly, I don't have a computer. We keep in contact through Facebook.
Do u and your mom Skype or face time each other?
That sounds like a good idea!
