Just given up after 3 days with my DS (2nd child), because in spite of his insistence that he doesn't need nappies anymore, he had nothing but accidents, and doesn't even seem to realise he's weeing, plus it was turning me into a screeching crazy person.
It did with DD too. I can cope with just about anything else parenting throws at me, but potty training makes me want to run away from home just so I don't have to do it.
Don't know when I'll get a chance to try with DS again before half term as we've got stuff on. He starts school in 2018 as well, so the clock is ticking....
