Thanks guys! I don't want to jump her right back into hard riding or anything at all like that. I just hate to think that I couldn't climb back on the mare at all until the foal is weaned. I bought her as a riding horse, and she just happens to have come pregnant! I am really excited about the foal, I just want to be able to "play" with my mare a bit too.
I do have another riding horse, so I can take my gelding out on "real" trail rides. It sounds like the biggest concern is keeping the baby out of mischief and following the mare (and keeping it short). So we'll see how it goes. I bought the book on imprinting and it has lots of good info on halter breaking, but as this is my first foal, I'm not sure how successful I will be at getting the little guy/girl halter broke right away.
Right now I am still riding my mare, and I am guesstimating she is about 6 1/2 months along. I hope to ride her on easy rides until she gets so big that I feel sorry for her. But right now she seems to be coping and enjoying our little outings. Everyone seems to feel that light riding is good for them, so I am hoping to do that until she tells me otherwise.
She is my brand-new riding horse, so I would like to enjoy her as much as I can, even though she is in foal. After the foal is born, I actually thought it might be easier on the mare, so long as the baby is able to keep up. I don't have an arena or pasture, so our only riding opportunities are neighborhood dirt roads and the national forest about 1/2 mile down the road. So that is why I am talking about trail rides.......it's the only place I have to ride! But we can go out for 10 or 20 minutes and come right back, so I will just play it by ear. Right now the baby isn't even born, but I am just trying to think ahead. Thanks for letting me ramble!
