In my case, I noticed that I was leaving behind my daughter's childhood. Sitting in front of a digital device (laptop, PC, iPad, iPhone etc.) is an exclusive experience and it excludes interaction with other human beings, unless they themselves are online.
With young children, the choices are stark and either/or in nature. Either you spend time on your device, which is taking time away from your child or you set aside that digital device and be fully present with your child. Of course we can let the child have their own exclusive digital experience so that we can have yours. IMHO that is the most damaging of all.
