There's lots of ways to amuse even a toddler under 2 with a computer. Browse through cuteoverload or icanhascheezburger. My favourite is to find a Flickr group like Animal Parent and Offspring and browse through saying what kind of animal and baby we're looking at.

On Youtube, one of the earliest interesting things, to a baby, is videos of other babies laughing or babbling, and other parents have uploaded a bunch of those. Of course there's more cute animal videos. Elsewhere, there's kids music videos by TMBG and others.

I'm sure there's lots more but I'm not usually so strapped for ideas that I turn to a computer. I have a sore throat and don't want to get up from the couch!
