Getting into the lifestyle after newborn

My wife and I have talked about this for years, had a couple of aborted starts. However we now have a kid on the way. Trying for a baby put a hold on any attempt to get into the lifestyle of course, but with a little one round the corner, I'm wondering if our window of opportunity might have closed for a decade or more!

Would be interested in hearing people's experiences of getting into the lifestyle after a kid
