A baby that is 8 - 15 months old we would expect that they're easily distracted. But they would be able to hold their attention for one minute or longer and typically for a preferred activity or an activity that involves a mother or father or grandparent, someone that they are connected to and enjoy the experience. A child of 16 - 19 months, we would expect that they could hold their attention to a preferred activity for 2 - 3 minutes. Once again, they can be easily distracted, so when you're doing the activity with the child, make sure that there is engagement from a person that they are connected to and enjoying the experience. By the time your child is two-years old, we would expect that they would be able to play alone with an activity that provides them with enjoyment for 3 - 6 minutes alone. They are easily distracted by noise and change in the environment, but if it's a preferred activity we would like to see 3 - 6 minutes of attention. When a child is three-years old, they can typically participate in a preferred activity for up to 8 minutes. They can also start to engage in a back and forth conversation and a shared experience during that activity. They may be distracted by the environment around them, but they will bring their attention back to the activity and participate for up to 8 minutes. By four-years old, the child is attending for up to 10 minutes. You will se independent play, creative play, and also engagement with an adult or with a peer, but staying with the activity for up to 10 minutes.
