I’m going to sound like a right tit posting this but I need help on where to start with potty training my 2 year old son 
I’m a first time mum and never grew up with younger siblings or family so I have no clue where to start on the potty training front. My son currently is dry when he wakes up in the morning but pees basically the second he’s out of his bed, it’s usually easy to tell when he needs to pee and he has recently started staying completely dry when we’re out in public or in the car on a journey. He stopped pooping outside of our home and his grandparents home around 8-9 months ago, so I feel he’s showing signs of being ready?
However my confusion lies in struggling to tell when he needs to poop. He has no tell tale signs when he poops, he just runs over smelling like poop and I know to change him. He makes no faces, no noise, doesn’t run away, nothing. This is worrying me when it comes to potty training because he cannot tell me or let me know when he needs to go. Does anybody have any tips on what I could do to change this? I’ve tried looking at other threads but I haven’t found much that’ll help and I’m terrified I’m going to be a useless mum and struggle to potty train him in the end
