We are only on day three of training and he is fine at home - potty in middle of room and he goes when he needs to. We were out for three hours this afternoon. He weed before we went out. Then I kept taking him to the toilet and sitting him on the portable potty all afternoon. He never did anything. Me and ds1 went twice in that time! As soon as we got home, he sat on potty and did a wee. Is it possible he was actively holding it all that time? Or was it a fluke? I thought children who were newly potty training had to get to the toilet fast.
