The Start of potty training?

Today Jacob had his 1st ER visit in a few months. He was dehydrated and got some IV fluids. They let him go home and he is doing okay. While we were in the ER Andrew kept saying he had to go potty...I ignored him because he never goes. Jack took him down to the bathroom and he peed in the potty! Then he went again about an hour later! So maybe tomorrow I will listen when he has to pee :-D
