Kids are a whole lot of work and stress, but they’re definitelly worth it in the long run. It’s so refreshing to come home from work and have 3 little girls wait for me at the door and when I pull into the driveway they start screaming Daddy! Daddy! Kids are as close as you’ll ever get to unconditional love from humans.
I don’t think it’s smart to put off having kids until you’re older because they are a major energy drain… you wanna do it when you have the energy. I’m only 36, and still wish I got married at least 5 years earlier (got married at 31). I’m not saying have kids at 18, but don’t do the dumb thing and put it off too long either. you might regret it.
