"I'm just not sure," said Dr. Marc Childs, who practices in Brewster, N.Y. "I usually find that toilet training works if you make the child think it's his need, not yours. My advice is, don't make diaper changing particularly enjoyable and reinforce others in your family when they go to the bathroom. He'll eventually get the message."
Dr. Peter Richel said that he did not see a downside to the alarm method, but would like to see more data.
"It's interesting and harmless, but the study is too small," said Richel, chief of pediatrics at Northern Westchester Hospital Center in Mount Kisco, N.Y. "Still, my philosophy is that if it doesn't cause the patient harm, then give it a shot."
The Nemours Foundation has more on toilet training.
