I know I have blogged about this before, but now that I am nursing twins I have finally had the impetus to purchase a set of these from CB2. I got the hour glass and the 15 minute glass to help G know when she can do things, all on her own. She's too young to tell time, and this way she can see how much time she has left, without asking me :) And she loves them! She loves to watch the sand, and they are bright and colorful and look cool in her room. And boy is it a help to me.
