I think you'll have at least one year (or more) to think about it. Depending on your spouse's attitude toward sailing now that the little 'peanut' is here in the world, and your logistics (opear/nanny/sitter) you may only be off the scene for a short while. Most regattas are family events, and your family will have a wonderful time with all the other families in attendence
If, however, your spouse thinks baby is more important than sailing, you could probably find crew around the sailing locations you frequent. Steady crew could be slightly more challenging.
If your spouse wants you home 'to be a family' all the time, sell the boat and crew for other skippers. It's a lot less aggrivation than watching your boat collect spider webs and dust..
Am I a bit jaded?
