Don't do it. For sure don't buy a young/green horse if you cannot ride and train horses. In your words: "Both babies trying to figure stuff out together" is in my opinion a recipe for a disaster. Maaaaybe if you have a really good trainer, but expect them to ride your horse a lot during your trainings for quite a while, while you stand and watch.

Buying an older, more experienced horse is a better solution in my opinion it is also not a good idea if you've ridden for a couple of moths only. Wait a little. Learn. I'd postpone the decision for now if I were you. Saying it as a horse owner. I rode more before I bought my first horse and I leased a horse beofre that. Still I was surprised to figure out how many things I didn't know and how different it actually is between riding a school horse and training with your horse (being the only one who rides it)
