We are in our sixties with health issues so are currently not seeing our grandkids 2 and 5 for weeks ahead. I want to send a little something in the post once a week to help keep them amused and as a little token of our love. Only inexpensive things. Have got sticker / work books, stencils to draw with ready to send. Any other little ideas we could post or order from Amazon? Grateful for any suggestions.
