DS (2.6) has been getting through 12 pairs of underpants a day since we started potty trainibg on Friday. He sits on the potty o.k. and will pee in the potty ,sometimes he acknowledges that he has peed but other times no reaction whatsoever.Am I trying to potty train him too soon or is this all part of the training? (He has got 25 pairs of underpants due to inclement weather on Fri and Sat).
