I had my two oldest grandkids overnight while their Mom and Dad celebrated their anniversary. It is a whole different atmosphere when they are here instead of the younger two. Instead of 'playing' we 'do' things together. Today, I pulled out some air drying sculpting clay. I will try to post a shot of what each of them made. I was pretty impressed.
What fun. And I'll bet the kids enjoyed the activity as much as Grandma did!! I'm with KWind...... My mother was like that with my kids too, and they do have great memories of it. Your grandkids will too.
That's great that you DO things with them! It makes them feel less like they need a "babysitter" and you really get to know them as you do the project. Fun!!
