Oooh thats a scary thought! Going to have to be a very well fitting wrap. No a nippa would 'bite' into the fabric, they are smooth ish cotton, not towelling. My woolley wraps might do it, but how to get it to stay in place while wrestling wrap on.....?!
Thanks tissy that was a helpful link, though mine are older than that. They have no leg gussets and I am seriously considering not using them because of this, my little one seems to need gussets to get any nappy to fit her. Plus she is extremely wriggly and pins scare the cr*p out of me!! The nippa definately won't hold em. I can see escaped poo and I'm not looking forward to that!
we had the nappies without leg gussets (five yrs ago now)-, and believe me they are great for a tiny baby, just not up to a heavy wetter! If you don't have Bumpy wraps (which do have a gusset)to go with them, then just secure with 1 or 2 nappy pins.
We also found the TotsBots Redwrap pretty effective.
