My 10week old DS is in Little Lamb pocket nappies using 2 bamboo boosters in each one. I wash and dry them according to the instructions- 30 degrees, less detergent, air dry etc. I change him around every 2 or 3 hours. They leak around the leg every day at least once, sometimes within the hour. What am I doing wrong? Does DS wee an extraordinary amount? Or are they rubbish nappies? The extra clothes and sheets washing is driving me mad. Help!
