Hi I'm new here and am looking for a little advice,I have recently got back into "horses",well I only ever rode bareback but that was nearly 20 years ago,and I have been doing some refresher lessons so I'm still a novice

I really want to get my own horse,but not 100% sure on size or breed? I'm 5"8 and 10st but I also want to teach my children to ride on it as well. Any help would be appreciated thanks Claire x
