Most of the people in our dojo have been back at class within a couple of weeks, myself included. I think so long as you're holding up your end of the deal otherwise, getting away for a couple of hours once a week is not a problem unless your wife/the baby is ill or if she just doesn't want you to leave. It's a real personal thing, though. Some people have had kids and essentially dropped off the face of the earth. My view is it comes down to priorities - you've got room for your job, your family and maybe one other thing - if kendo is second to some other hobby, it will get short shrift.
