We play a card game that requires holding several cards. These card holders are a huge help. I really like having multiple colors.

My daughter loves her blocks. She will get them all out and look at each one until she finds her favorite. She likes to shake them and see what each one does. These are cute little blocks that have hours of imaginative playtime inside. They also have blunt corners, so no sharp edges like wood blocks for the safety of smaller children. The fact that they have the letters of the alphabet and a corresponding object inside makes them a great learning tool even for older tots. We have really enjoyed these and recommend them to our friends.

Dr. Jeanne Shaw is an outstanding mentor and guide in the area of human relations and relationships, as reflected in her handbooks. From her decades of experience of counseling individuals and couples come the vital lessons that she has compacted into this handbook.I have learned so much not only about relationships, but about life and living from Dr. Shaw, that I remain eternally indebted to her.
