DD2 is 21 months and for the last while has been telling us everytime she does a poo and sometimes when she does a wee, she seems to recognise when she is doing a wee when her nappy is off just as it starts to come out. We put her on the potty occasionally and she is doing wee's more frequently on it. I wasn't planning on training her for another six months but now I think she might be ready????
