I'm using 7th generation diapers, and I just bought size 2 for my 7 wk old son. I think he weighs about 12 lbs now, but haven't had a weighing since his 1 month appt.
I'm still not sure if they are too big, but I he was leaking with size 1's so I thought I would try switching up.
What size are you using for your 7 wk old?

We aren't at 7 weeks yet (will be 6 weeks on Friday), but we just went to a 1 about a week and a half ago. We weighed him on Sunday and he was 10.25 lbs, so I don't forsee him going to a size 2 for a little while longer.
