Reading corner - I love the wooden letters (from JoAnn's painted white) the framed book covers. IKEA spice racks painted white for the bookshelves and dot rugs from IKEA. I would love to do this in a corner of our family room!
Our nap time routine chart (sleeping train) that tackled the requests and got our 2 year old to learnto take a nap by himself in 3 days. He used to require us to stay in his room until he sleeps and would thus expect us still there when he wakes.
