The velcro on some of our long serving Bumgenius nappies has seen better days after four years of constant use by 2 DSs. I'm loathe to buy new nappies as DS2 hopefully has only another year in them but they're coming unstuck and we've had a few nappy around knees moments. Is there any way to revive it? Or do I need to unpick and replace? Wish I'd known better when DS1 was born or I'd have bought them all with poppers as the popper ones we have still look like new!
