I know they advertise that their size 1 goes to 18lbs but I just unsnapped my duo wrap to the largest setting and he is about 11-12lbs at 5 weeks. I want a few duo diapers but don't know if I should invest in size 1 or wait until size 2......
How big were your babies when they outgrew size 1?

she was out of size 1 by 6 weeks.
