In reply to ericinbristol:
Oh we haven't had that problem. We create a space where toddlers and parents can safely challenge themselves with climbing the wall, gym ropes and playing on swings. The session is 2 hours and we have lots of regular parents who stay for the whole two hours.
We do have toddler specific climbs and shoes and we sometimes add more holds to the wall for the session, we are hoping to get a ladder (monkey bars) and cargo net to develop the climbing equipment/games.
It really is a great session and even a toddler that only engages in the climbing for 15 min and the toys for the rest is at least doing 15 min more climbing a week.
