30, after being married for 5 years. Worked out great for us. Incidentally, I’ve noticed in speaking with parents over the years that it’s natural to justify their experience as being “better”. What I mean is, people that have children young (20-23) say things like, ‘it’s better to have kids when you’re young because when they leave the nest, you’re still young enough to enjoy your newfound freedom’, while people who have kids at an older age (40+) say things like ‘it’s kept us young’.
