The best part about an activity center is that there are playing and learning that happens simultaneously. Even when your child is small, they can grasp a lot of different things such as shapes, colours and more. With the right activity center, it gets easy for them to process all of this. It all depends on how good the center is and how much time your child has. You can start them off with a good one when they are infants, so they latch on to the idea. As they grow, keep investing in better ones, and refrain from other toys. You can instead focus on more books to ensure the learning keeps happening. At this stage, most babies love the idea of discovering new things, so it will never bore them.
