DS is 3.3 After a couple of false starts we went for after his 3rd birthday. He was nearly there about a month ago - mostly going independently for pee & poo. But he has had an almighty regression. Today nursery called me to pick him up early as he had 3 accidents in an hour. Had him @ Dr & no sign of infection. In total he has had 6 accidents today & has been in a pull-up since 4 o'clock. Up to now thought the regression was an attention thing - he is middle of three all close together, but after today just don't know anymore. Anyone got any thoughts?
