My post did not say anything about how I was going to use the computer, in fact we often do exactly what you said with his fake keyboard in between his other activities.
I also believe that it's my job to provide my children with the environment in which they can thrive and be independent. This post is asking for constructive guidance on how other people have navigated the transition into engaging with technology that all kids go through.
If you have any ideas, I'd be happy to hear them.
