That's the thing, isn't it, Arimeh? It's not like you see 20 year olds in nappies, so they do learn to TT at some stage. What does it matter if it's 12 months or 48 months? My mum was convinced Charlie wouldn't TT unless I 'forced' him. Who in their right mind forces a kid to TT?

My sister's DD only became completely TTed at almost 3.5 years of age, despite my mum putting her on a potty religiously since she was 12 months old. I don't think it's politic for me to mention to her that Charlie will probably TT around the same time despite me never 'forcing' him to do anything.
