I agree Daniel Tiger is great for targeting particular challenges with those little sing songs they do to help kids learn and also targets a slightly younger audience. When we were having our 2nd and our 1st was 2 years old we played the baby episode a few times "a baby is coming to our family...". Our son welcomed our newborn daughter perfectly and somehow even found a little red book to (almost) drop on her.

I love that this post is on HN. It's helping me frame why I like Bluey so much. I'm also going to try that Sarah and Duck mentioned elsewhere.
