ur better off leaving her to her own devices, stripping is only needed in extreme cases, only thing to do is remove her once she has definetly spat them because I can't think of any african that wouldn't appreciate a quick and free live feed.
Only strip if she is suffering from malnutrition, and can't handle holding anymore.
It is also habit for them to release the fry and suck them up again once they get to a good size and when she starts to feel secure.
I'd leave her be. if it's her first time it won't be the biggest batch and she will need to gain the experience for next time.
