Why do babies like to drop things?

Babies are learning to grasp objects, so they are going to drop things pretty often. If baby drops the same object twice in a row, it is time to pay more attention to them as they are trying to get your attention. My son loves dropping his teether on the floor. I will pick it up and make sure to let him know that he should not drop it. There are times where our eyes meet, he will deliberately drop the toy on the floor and held his hands up. This means that he wants up! But do not let this behaviour become a habit, after picking the toys up for them maybe say twice, remove the toy. So that they will know that when they drop it, it will be taken away which will stop them from doing it.
