Hi, I split this topic off from the sticky so more people would see it.
A small shatterproof mirror is a great toy at this age. Also, if he's having trouble grabbing toys, try giving him bigger things that he won't have trouble getting to. My LO loves to lay on the floor and roll around and look at things. Her sister and I going about our usual business are apparently all the entertainment she needs some days. She also likes it if I help her grab things -- you can hold toys that are easy to grasp up to his hands so he can grab them and bring them to his mouth. With practice, he'll get it!
