Well, that was a lot of honesty... I guess. But none of that was reassuring in the least. I have a support system behind me, my mother, in laws etc. Even if my husband decided he didn't want to help, not that I would willingly give him that option. But still...
I'm not sure what you expected.... we're mothers and having a kid changes you forever. Life is not rainbows and butterflies, you find that you are completely and utterly responsible for this tiny lil thing who despite being the size of a loaf of bread, completely rules your entire day!
A full-time job generally takes up about 9hrs in the day minimum. An hour riding session isn't an hour since there is grooming, tacking and so forth and so on... so add in another hour for that (and more if you don't have full care boarding). Then you still have all the other things in normal life like commute time, shopping, cooking, cleaning, laundry, sleeping AND you now have a child that needs attention during all of this! Won't even get into the fact that sleep basically flies out the window for the first couple months (or longer...).
A child can accompany you with things like shopping and certainly can be around and attended to while you get household chores done but they will take longer (sometimes MUCH longer) but you can't throw them in a playpen and go ride for an hour. A lot of barns aren't safe to even bring them at all, once they are walking.
Life with kids + horses is WAY easier if they aren't boarded IMO. When the lil one finally takes a nap or goes to bed for the night, you can bring a baby monitor outside and listen while you ride. You can park a stroller w/kiddo in the barn since there aren't other people/horses milling about. You can build a secure play area next to the arena and so on....
I wouldn't trade either of my kids for anything but time-consuming they most definitely are.
Oh and when they get older.... it's WAY easier to ride since they are off doing their own thing UNLESS their own thing requires you to be the coach, chauffeur, team mom, etc... 3 days a week, I now drive 45mins each way and then sit for 1.5hrs while my lil girl WRESTLES!
She has a very adorable safe pony but oh no.... apparently squashing lil boys into submission is her thing, so there I am cheering her on and hoping they don't squash HER!
