hi R., i don't have a boy but what my sister in law did with her boys.was she would limit intake of fluids then she put a boys pull-up on him which you can buy at any grocery store. then on top of the pull up she would put a pair of his choice of undershorts on top. then she told them when he can stay dry all night then he gets to take off the pull-up and just wear his shorts. but she made it a big deal. putting a diaper on made them still feel like babies. the pull -up made them feel like bigger boys because they can just stand up and step into so good luck hope it helps.
