does anyone have any wool they can spare?

My dipe collection is mostly fitteds with fbs at night, and the only way we don't leak at night is using wool, now we have been using fitted during the day and I bought a few large wol soakers since his dipes are large, but they are way too big. My son is just under 20lbs. He is 11 months old. I don't have any $ to get more. If anyone has any they can spare, we would greatly appreciate it thanks.
