Ds2.5 is so happy in his nappy he won't say if he's wet or even if he's done a poo. He will happily walk around in a dirty nappy, so I have to keep vigilant. I'm worried as he's almost 3 and still shoes no signs of toilet training. His interest in the toilet extends to barging im on people and that is it. I've tried sitting him on the toilet every so often with the tap running to see if anything would happen and help him make the connection but nothing. Has anyone else had a son that just didn't care? What helped them to connect toilet time to what was happening in the nappy? How do you make it is they don't like sitting in a dirty nappy? He seems to me at times to struggle to connect things, for instance I've tried piquing his interest in toilet training with promise if Thomas the tank underwear etc but he doesn't seem to put it together, nor the whole little boy/ big boy concept. Perhaps he's just not ready? When should I worry? Thanks!
