you say you're using the newspaper fold and wing out the back. Do you also wing out the front too? I find I need to do this with my 24m dd, at 31lbs. However, I'm still using the standard size CPF and wondering if hers are getting too small. I still have room to fold over in the front, though. Anyway, what I'm saying is this: try just the CPF lengthwise, folded in thirds, lay son on top, wing out the back and front for pinning. Does that help? Good luck on your ventures! I also do not pin as much as possible, and I use Bummis, and side snapping covers without problems.
