Any suggestions on how to start teaching my son new things, for example colors, shapes stuff like…

Lots of repetition. Point out shapes and colors in books, or physical objects like blocks.

I let my son watch Sesame Street, Blue’s Clues and Barney which taught him basically everything. We also play the Sesame Street soundtrack everywhere we go😑

We have lots of books and cards as well!

Simple songs on YouTube helped my kids with colors, numbers, shapes, animals, etc.

Books!

Repeating what you child loves works

My daughter love bath toys sp I say blue finish brown otter etc and she says bluuu fa and brr ott lol

My son loves the shape sorter toy. We play and I talk about their color and while he watches I use my finger to run along the sides and repeat over and over what shape this is. Also books. I don’t rely on music or tv to teach him. We watch no tv. I’m constantly interacting with him and teaching him in real life situations. I’m always talking to him explaining what things are and what I’m doing and why. Little ones are truly like sponges!
