V.A.
Just wait for him to come around. Boys usually tend to take longer to train. I learned that the hard way with mine. I have 4 children and trained 2 girls by the time they were 2 then I had a boy and he had no interest in training and then just one day at 3 years and 2 months almost exactly it was like a light bulb came on and he started doing it. The peeing came first and I left him with just a long shirt on and nothing on the bottom for a whole week and (it was a messy week!) We got the poop down and he started doing both in the toilet. So just be patient. Numerous people told me that when I was going through that period that boys don't usually train completely until 3-5 years old. I now am waiting for my 2 year and 5 month old to start taking interest, (which he has none yet).
I hope this little bit of experience helps. Don't get frustrated. He'll come around.
Take care!
