I totally agree caliber! I have been a nanny for over 10 years. One of the first thing needed to establish is their security. Without feeling secure, their learning growth is slowed greatly. Our time spent playing with them does both, helping them feel more secure and happy. When a child feels secure, they start focusing on the other things a child should be... learning, observing, and just having fun. Then they end up entertaining us during our time spent together, nothing greater! :) Great post!
