My 31 month old son has been potty training for 10 days. The first 6 days we stayed home and he was perfect! No accidents. Once we began making outing outside of the home the accidents have been happening in spades. I have tried gating before we go places. Taking him back to car every 15-30 minutes to tee-tee on our little potty. He is still having accidents on himself. He will not tell me/Sunday school teachers/preschool teachers he needs to go. Even when his teachers all are directing him to potty at least once an hour. I make him clean out his wet/dirty underwear in a bucket when we get home. I am getting more and more frustrated with each accident. What do I do?
