From seasons 1-6, this is an amazing anime I can't recommend enough in the genre.

Also known as 'Kimi to Boku'.  It's very chill and focuses heavily on the lives of the characters.

Daily slice-of-life with cute kids?  This is certainly that!  The first episode is a little on the sad and dramatic side, but for the most part it's a sweet series.

Pure serotonin in anime form. 

Quite dramatic considering that the protagonists are a 10-year-old and a 1-year-old, but they wind up learning and growing as they find themselves in various situations.  Older anime, but still good.

Another older anime on the list, but a cute mix of comedy and drama involving two teens who find themselves having to take care of an alien baby.

Girls in a band and just being girls.  Light hearted, includes music, and is a feel-good anime for the list.  Sometimes it's calm, but most of the time it's energetic.

Another fun and energetic slice-of-life; this one is lighthearted and wholesome.  It just has an entire 'feel good' vibe to the series from start to finish.

Cute and light-hearted.

Cute hamsters, cute adventures!

There's just something adorable about this.

A very chill anime with a slow yet steady pace.
