(I was a mostly TV-free toddler, because my parents didn't have one until I was 6 - though I'm pretty sure we were glued to it whenever we visited anyone with one - so I am saluting my own mother here too)
All our TV is streamed, so we do have to put a bit of thought into what we watch, and I have no idea what is available on broadcast TV for kids. But we've worked out a few things that are not only fun for small people to watch, but are at at a minimum tolerable for bigger folk - and ideally enjoyable. I thought I'd share our Youtube favourites in case you (or your toddler) are having one of those days - and if you have any great discoveries let me know so we can diversify our playlist.
It's an oldie but a goodie. The Little Monkey loves the furry monsters, and I love the celebrity clips, because they're often a bit clever (Sesame Street intentionally try to make their shows appealing to adults as well, so that you'll watch and interact with your kids - very sneaky of them but it works here!). The songs are the best, and we know quite a few of them off by heart now. A few of our favourites are Dave Matthews and Grover; Oscar ft. Macklemore; One Direction with the letter U; and Usher's ABC song.
