My husband says I should be on the horse by now, but I'm perfectly comfortable going at this pace.
Going slowly really pays off. I had my horse for a year before we re-started her under saddle. For a full year, we did ground-work.
Then almost another year doing lunge-line lessons.
Only recently are we riding on our own & I am certain my confidence comes from the fact that we took our time & didn't rush. She had been rushed before & that's not the right route for her (she's a big draft horse---slow & steady is her "thing")
Nothing wrong with taking all the time you feel you (& the horse) need!
Enjoy every minute of it!
