Timeline of the Little Nightmares games (remembering that it's just a theory of mine using the clues the games gave).
I'll only be counting the games here, so no podcast, novels, or comics.
First: Secrets of The Spiral. In The Backstage DLC, we see the Puppeteer brushing the hair of a girl with a ponytail, and we also see a yellow raincoat. And do you know who else has these two accessories? Exactly, the Yellow Raincoat Girl from Very Little Nightmares. Since the Backstage is located in the Carnevale and the Carnevale has several balloons, I theorize that the Yellow Raincoat Girl escaped from the Carnevale and ended up at The Nest via a balloon, as we see at the beginning of Very Little Nightmares.
Second: Very Little Nightmares. It's already a consensus that Very Little Nightmares takes place before Little Nightmares 2. In this game, Six didn't have her yellow raincoat yet, which practically confirms that this game takes place before Little Nightmares 2.
Third/Fourth: Little Nightmares 2/Altered Echoes. Altered Echoes seems to take place during and a little bit after Little Nightmares 2.
Fifth/Sixth: Little Nightmares 1 and Secrets of The Maw. I don't think I need to give many explanations here.
Seventh and last (for now): Little Nightmares 3. At the end of The Shores DLC, Low and Alone still didn't have their weapons, and the location they go to after crossing the mirror doesn't seem to be the Necropolis. I believe Little Nightmares 3 takes place after Little Nightmares 1 because the Guests' boat ran aground in the Necropolis.
