You’re married, do what makes you guys happy.
That advice isn't going to change.
Look at your budget (daycare or staying at home, medical expenses, supplies and clothes and diapers), decide what goals you have for the immediate future (travel, more pets, buying a home, career advancement or change, etc.) and decide if it makes sense to try for a baby now or when you're older.
And remember that there are no guarantees in life. Even if you're young and healthy you may not be able to conceive for a while if you start now, or you may not ever conceive. The risks increase a bit as you get into your 30s, but that doesn't mean it's necessarily wise to get knocked up at a young age to prevent that. Again it's all a crapshoot ... plenty of healthy 23 year-olds have trouble conceiving or maintaining a healthy pregnancy whereas someone pushing 40 may get pregnant with no problem.
It also depends on your lifestyle. My husband and I like to travel, but aside from that we're home most nights and don't really have a ton of obligations outside of work and occasional family gatherings (they all live close by). So when we had a baby at age 33 it didn't really affect our day-to-day too much ... paying for daycare was the only MAJOR change, really.
Meanwhile we have friends who are *constantly* socializing and attending events and spontaneously going to concerts or parties or traveling ... they seem to have decided that kids aren't for them, and frankly I don't blame them because a baby would be a HUGE disruption to their lives. I know another couple who was in a similar lifestyle and they had a couple babies and now their marriage is failing because they just couldn't make the adjustment, because they weren't prepared to give up that "carefree" lifestyle they had before kids.
Again ... do what makes YOU GUYS happy, and what makes the most sense for YOU GUYS. You're never going to be 100% certain it's the right time; you're never going to be 100% prepared in terms of finances or the right house or picking a good school. But at some point, if you would like to have a family, you'll know when you think it's the right time to just jump in and see what happens.
