W is younger by a month and I'd say taht only in the past 3 months he's expressed any interest in the telly, and that is mostly theme songs. In the past 2-4 weeks, he's started sitting and watching for maybe 10 minutes at a time (as opposed to trying to pet the screen, watching 30 seconds before running off for a toy, etc) - which is a bit worrying for me. It's been a good background half-hearted distraction for him, e.g., when daddy goes to work in the morning, but I think he's now getting happier to watch, which make me worry it's on too much. (skulks off to hide her lazy mummy-ness...)
I'd say it's nothing to worry about, and actually a blessing in a lot of ways.
