> I have read other posts about climbing with kids here so I take it they're allowed in other gyms? Any advice on how we could carry on climbing as a family? I was thinking maybe get our own insurance so they don't have legal concerns?
It really depends the wall and their rules, it's there place after all and they may not have any flexibility due to insurance/legal issues. I doubt very much the wall would have any kind of different view if you had your own insurance but I guess you can always talk to them.
We've had mixed success taking ours climbing. I can't state this forcefully enough but you've got to be supervising them 100% at all times and frankly at that age they have a limited attention span for climbing so your wall trip might not be as productive as you might hope.
We did bouldering rather than anything with ropes as you can't really supervise them appropriately when climbing with ropes. As they get older it does become feasible, we get our five year old to stay in one spot and second the rope and she does that responsibly. I wouldn't do this with all five year olds, it really depends on the kid and it also depends on how they are behaving at the time, you are the best person to make that assessment but if it's not working then it's not working, be prepared to change plans.
With bouldering if there's two of you then you can tag team them and have one person dealing exclusively with your toddler then swap about after a bit, a bit like climbing with a baby which it sounds like you've done a bit of. This works to some extent but it losing the whole family climbing vibe as you're not all climbing together. Also my partner struggled to concentrate on her climbing when there was a needy toddler about, although I managed fine!
Climbing outside is a good option but again don't expect to have a productive climbing session, I've found the best approach is to think of it as a picnic where if you are lucky you might get some climbing done. They don't need much of a challenge at that age, you need to be somewhere where there are just some rocks rather than proper routes of problems, often they just can't reach between holds on normal routes.
As it happens our local wall is fine with young children, they do kids clubs from 3 years old which is really the earliest they can really do much. I'm not sure if they have a minimum age, they've never approached us to say we couldn't climb with such a young child so I don't think they do. Like all walls though I'm sure they'd have a problem if we weren't supervising our kid appropriately but we've always had a good handle on that, we don't want our child crushed and we don't want to spoil someone else's climbing session.
In summary it's possible, you need to find the right place and don't expect to get a lot of climbing in yourself. If you can find a kids climbing club it's great because you can do a bit of family climbing followed by 30 minutes of something more geared towards yourself while they are in the club followed by a bit of family climbing until you realise it's time to go!
