I’m always amazed at the folks who were able to get back in the saddle so quickly post-delivery. For a different perspective, I think it was probably 6+ weeks before I was in the saddle again, and honestly, between exhaustion and time (returning to work, and baby was a terrible night sleeper for over a year), I think I rode maybe a dozen times in my son’s first year, and that was with having my horse at home. I free leased my horse out to someone else so he still got attention and some exercise, but it wasn’t until the following year that I got back to riding in earnest.
Other caveats- We don’t have family close by who were able to swing by and watch baby for an hour or 2 while I rode, baby was not the type to tolerate just being set down in a stroller or pack and play while I rode, and with daycare costs, extra $ for a regular sitter wasn’t an option. So, depending on your network and budget, that may be easier for you.
Another consideration- baby is only small for a short time, they grow fast, so you may not want to spend as much time away.
