Ds was 5-15 and dropped to 5-7. He fit perfectly in nb grovia and xs sposoeasy aios. I used KL0's too but was a little paranoid about covers rubbing the cord. Bummis super brites fit from birth.
What didn't fit - thirsties duo diaper (fit perfectly after cord fell off), bummis super lite, nb simplex.
