So I’m new to cloth diapering and being a mom. The cloth diapers work amazing for one of my twins but they leak real bad for my other twin. They are the same weight (11 pounds) but the one with the leaking issue has skinnier legs. I put the diaper on him just the same as his brother. What can I do to fix the leaking issue? I can’t afford to buy different sizes. I’m using Alva baby with charcoal/bamboo inserts and microfiber inserts. He leaks with both inserts. His brother doesn’t leak with either.
