My daughter works full time and I babysit her son once a week to help with nursery costs. He has just turned 3 and is in disposable nappies full time. My attempts to potty train are failing. He is just not interested. My daughter was out of nappies full time at 18 months, and my son by 2.5. In that time I used terry towelling nappies with plastic pants over. I think it helped with potty training, because they were aware of being wet or dirty, and told me. My grandson is totally oblivious in his disposable nappy. I am minded to buy some old fashioned terries and the pants if they are still available, which may solve the problem. Any other suggestions?
