8 week old- what are the EC signs parents give when on potty?

We’re having a 50% success rate with our 8 week old. We do the toilet when he’s showing signs or after a wake or feed etc. we do the Cues: pss-pss" for pee or a grunting noise for poop) but are there hand signs or anything else we do as baby gets older??

He pees almost every time and we’re catching some poos. Thanks for any tips!!

Also is this too little to start??
