You can put together a Mass tote with quiet toys, books, a few crayons and a coloring book, that your child only sees at Mass so it has a bit of novelty. I always tried to keep the theme of the items in the Mass bag Christian (soft saint dolls, angels, prayer bears, books and coloring books with a christian focus etc.). What is the difference between these distractions and screens? Well, there is something about screens that can become addictively entertaining. There is a certain passivity that takes over and the brain becomes less active. Our entire society seems to need this stimulating entertainment all the time so much so that things like quiet prayer, the ability to use the imagination in contemplation about God, the ability to philosophize and reason gets more and more stunted. Those things don’t seem quite appealing to the screen addicted brain. It may not be readily apparent but this inability to be at leisure and to just think, imagine, pray, read a book quietly, create art and contemplate sort of stunts our spiritual life. Our brains get rewired to be passive rather than active and I really think it affects our ability to pray and to hear God. I know all these things may be above the level of a 2 yr old. but I think that play, use of their imagination, looking at pictures in books that they can really study and that are not constantly moving and even their primitive drawing are all goods that will develop (if encouraged and cultivated) and serve their ability to know and love God in a deeper way as they grow.
