In reply to scragrock:
I've had so many close calls, the worst being at Beacon in NW when upon finishing a problem I looked down to see a toddler sitting 4m below me. The mother nearby strolling her pram along, also the matting, was alerted by my partner while I hung around, said mother then looked up at me, saw the child and just smiled, kept sauntering along past before calling to her child to come along, unfathomable lack of care.
I'm also not a fan of infants being carried around the matting by a parent, especially as it often happens on a busy weekday evening here in Bristol.
Seems to me wall staff just need to be more stringent with minimum age rules and enforcing them. This is usually well done in centers where there is lead climbing but not so in bouldering specific gyms.
