When my sister and I were kids, we got horses. Well, I would ride my bike down after school every day and take care of mine. My sister would go every day, then every other day, and before you know it, almost never.
Because I was picking up her slack, my parents said that her horse was now mine. Well, she pitched a fit, so my parents said if she could take care of it every single day for three months, she could have it back.
Didn't last.... so the horse was again mine.
Sometimes these are life lessons.
You have to work for what you want.
Therefore, if it were my daughter, I'd start compromising. Does she want horses? How many is she willing to work for?
Horses are very time consuming and expensive. If it's not a priority for her and it's a burden for you, start selling some off. Maybe if there are many less to work with, she can find time for just one or two. And if she can't, then move them along. There are always more horses, and she can then work off/earn money to buy one when she is old enough or willing to work for them, if it's what she truly wants.
My parents were willing to give my sister and I whatever we wanted, but we had to WORK for it. Whether it was taking care of it, or earning straight A's and B's in school to earn it, or whatever.
It carries on... I am dedicated to my animals, I take care of them rain or shine, sickness and health.
I take care of my truck, I worked for it and now even though it's paid off I make sure it's washed and the oil is changed and anything is taken care of immediately.
I dunno. But I myself don't have kids. Only know what my parents did, and seems to have worked
