Bluey is amazing, warm, funny, clever, just perfect. Any kids show that can tell the story of human evolutionin, while using it as a metaphor for children growing up is pretty special. (I think that episode is called Flat Pack)
And also, if you can access iPlayer (BBC), Hey Duggie is brilliant, silly, funny, great design and sweet. Also Puffin Rock (Netflix) is like a warm, gentle blanket - but sneaks in educational nature content, as does Octonaughts (iPlayer / Netflix), which is also excellent.
