First off, we are incredibly big fans of Melissa and Doug toys. Many of their great products have found a home in our house for years. We had very high hopes for this clock, and perhaps it is partly our fault for waiting until our son was almost 4 to introduce it to him. We truly wanted this as a teaching time toy, as he already knows his numbers and shapes. We had two problems, first, the hands do not stay in the clock face. I'm not sure if this is a universal design or if it's a fluke on ours. Also, when I try and hold the clock face vertical or almost vertical for demonstrating to our son, all the puzzle numbers fall out easily. Little things, but those are the issues my family had. As such, it became just a puzzle of sorts, which lost my son's attention after about 1 minute.
