Activities?

Now that the hibernation season is coming, I'm trying to come up with more ideas for activities to do with the kids. Most weekdays I do a special activity just with Berlin while Elijah is napping because it makes the activity go a little smoother. And some nice one on one time with Berlin. But I'm trying to find some more ideas on what to do for both ages and abilities. I've been looking online but if anyone comes across any mom sites with fun ideas... let me know :)

thanks! now onto my fun activity time with Berlin!
