One thing that is true for both my boys is that they love to hoard little things. Little plastic horses or animals, Lego mini figs, Playmobil guys with all their little accessories. Ever since I allowed them to play with little things without fear of them swallowing them (although I'll find my almost 7 year old with something in his mouth occasionally what's up with that?) they loved collecting them.
I'm sure you can relate to finding who knows what in the washer or dryer if you forgot to shake out little boy jeans before putting them in!
One of my boys thought that he needed to collect something so he decided to collect rocks. Problem was they weren't pretty little rocks, they were fairly large regular landscaping rocks. I decided to record this little collection of his no matter how silly I thought it was. I think he'll like to look back and laugh at it someday. I know I will!
Do you have a collector in your house? Have you recorded their collection yet?
