As I am such a hi-tech guy, it may surprise you to know that I use very few devices in taking care of the baby.
Chloe gets .5hrs of TV in the afternoon and .5hrs of music every couple of days. That's about it. Elizabeth cranks up all the cool stuff at night, but during the day its just me singing, giggling & playing baby games with some rattle toys. Sure she sits at my computer desk a lot, but that is just text with a very few Youtube videos thrown in. Might just as well be a glowing encyclopedia on a book stand as far as she's concerned. We've recently started short trips out back to look at the flowers.
