Haiya, my 2-year-old was exactly the same, so sikit je dapat tenang lah, this is pretty normal at this age! A few of us mums went through this phase where the kids would do those little "sekali teran" poops throughout the day and didn't like the feeling, and honestly it just takes patience and time before they're ready to communicate better. For the toilet training part, I think it's still abit early to push too hard since he already knows how to pee on the potty, most kids aren't consistent with poo training until nearer 3 or 3+ years, so ditch the pressure first and see if it naturally comes when he's older and more ready to tell you. In the meantime, just keep the potty accessible, celebrate the wins, and clean up without drama so he doesn't develop anxiety about it. One of my mum friends just let her daughter go in the nappy for now and slowly introduced sitting on the potty fully clothed just to get comfortable, then after a few months it clicked, so maybe try that gentler approach first?
