I don't know about how much they will hold, but wanted to caution you about using pull-ups. They are just glorified diapers, more expensive and they inhibit your child's progress with toilet training. When you begin toilet training, keep your son in diapers until you see that he is having alot of success with him telling you that he needs to go potty, then change him to regular underwear. I have experienced this with my first born and many of my preschool students. Also utiize a reward of some type to motivate him to want to try.
