Lea, have you tried putting a booster between the nappy and the cover (or longies), at the front of the nappy (where little boys pee)? Apparently that is very good - it is what I'll be trying for Jack as soon as the boosters arrive. Also, are the nappies you are using new? I can't believe the difference in absorbency I'm getting from BBB between 3 washes and 10. Jack was wetting through them quickly, now he can go a few hours in one most of the time. And the only difference is they have been washed more times.
