For whatever reason, this morning DS (26 months) ended up nappy-less while I was brushing my teeth this morning. I could tell he needed a wee so said "Don't wee on the carpet!". He came and tried to get in the bath (he wees at bath time a lot!) but couldn't so instead he climbed onto his step and weed into the loo! Wahoo!
Totally get it could just be a fluke, I was imagining potty training much closer to age 3. I don't see the point in trying before he's ready and failing. I was planning on waiting until he's definitely ready.
I don't want to overwhelm him - recent/upcoming changes he has:
Starting nursery next month
New brother in November
Just moved to single bed
Just got rid of bottles 
Our only loo is upstairs, could get a potty for downstairs but if he's weeing standing up at the loo upstairs, wouldn't that be confusing? He knows when he needs to poo I think but I should probably start paying more attention.
If you think I should go for it, any tips? How does one potty train somebody? Thanks!
