If your child has given you any hand made gifts in the past, this is the time to dig them out of storage, and display again with pride. Tell your child how much you like it, and how glad you are that he took the time and effort to make it for you, and how it makes you feel loved. It is also fun to show them their growth and development if you point out how much bigger his hand is than when he made it, or how much more detail she includes in her artwork than she used to.
Displaying it shows the value you give the items, and the message won’t be lost. However, if you give verbal messages as well, the learning increases exponentially. And who knows--once they realize how much you like it, they might just want to make you something again.
