Army wife, they are right about 19 months now. We've set the saddle on them (but have not buckled (just roped the buckle around) them. I will not let anyone on them until they are closer to 2 1/2 years. When they turn 2, I will saddle (and buckle), but from my understanding, the longer you wait to put weight on them, the better their bones will be.. so I will wait to as close to 2 1/2 as I can instead of 2.
Thunderspark, when we first got them, mom and baby were a fight. If we pulled one out - it was constant hollering for each other. If one didn't call back asap, they would run wild looking for each other. Now, they are fine! It took awhile, but mom weaned on her own with a little help with us pulling them out for a short while each day to separate them some.
I am fairly sure we have them where they need to be (for their age).. I really think actually saddle breaking them will be a breeze when the time comes. I think they are going to be amazing!!
