I rode up until about 7 1/2 months and only stopped because of too much ice and I was afraid that the horse might slip and fall, if not for that I would have kept on, I still did all the barn work, cleaning stalls and slugging bales etc. right up to delivery time.
I had an easy delivery, the first labour pains were 5 min apart and by the time we got to the hospital they were 1 min. I had my daughter before noon.
I didn't start riding as soon as I would have like, had to wait for a couple of months mainly because no one to babysit for me.
Later my daughter was in a play pen in the riding ring with toys and I schooled around her but only on my very trusted mare, no rank horses at that time.
When she was around five I put a little "rumble seat" on the back of the western saddle and we both went out for rides, me in front and her behind, often we would come back with her in front and me behind.
