My baby loves to watch short videos of kittens and puppies online. Is that OK?
If you're enjoying them together and keeping your viewing sessions fairly limited (those videos tend to draw you in for longer than planned), it sounds just fine. Your baby is enjoying the closeness with you as much as the videos.
Extend the experience by visiting a neighbor with a friendly dog, getting books on baby animals, and practicing all the animal noises you can think of. At this age, you want to make media a shared experience and an opportunity for learning.
