Great new section, will make for good reading
As for the potty, keep putting your ds onto the potty of toilet ever 15 mins. You did ask did he need a wee and he said NO, but at the start they cant feel when they need a wee also some kids dont know when its coming, its running down there leg before they realise.
The best thing is bring to the loo every 15 mins will cut this down, but it wont cut it out, they will still have accidents.
No your not being too hard your just a stressed out potty tranning mum xxxxx
Good luck and it took my ds about 2 weeks for the penny to drop
