Like most situations in life, it takes a village.
I’m fortunate to be at a private facility where I don’t have to be in the training program and the care is good enough. Not as wonderful as if I were doing it all myself, but I’m confident the horses aren’t going to die the 2 days/week I’m not there.
Just this morning, the resident trainer came in the arena with a newly arrived 3 year old and got on him for the first time (first time she was on him, he’s had rides before). The other 3 of us just stopped working and walked while she got on and he walked around. Once he was settled, the rest of us went back to work at the other end of the arena and gave them lots of room. At the end of the ride, the trainer thanked us all for the consideration. It’s great being with like minded adults!
It helps that it’s a smallish place with most of the horses belonging to the owner.
The previous place I was at had too many unsupervised kids on unsafe (IMO) ponies for my tastes. The week I left, 3 kids came off in a group lesson within 10 minutes.
