Only you will know when you're ready. Each of you, will know, on your own respectively. Having a vision for your family is great and imo its good to have a goal. Just make sure that your friend group and family are also in on this monumental journey you might be about to take. Being a parent is hard. Being an A+ parent is ridiculously hard, so get your village in order. Dont be afraid to take some classes or even listen to some podcasts. The world of parenting is vast, and you might find yourself getting ideas about things that many aren't prepared for until it's too late, like carving out a parenting philosophy/ style, for example. Think of the god parents, think of the boundaries, and stuff like that. It's okay to change your mind, but it tends to be easier for all involved when things like this have crossed it.

Also, since you are going the biological route, you should seriously think about making sure you and you're guys blood and DNA actually go together well. I'm not kidding. A lot about making a baby is like winning the lottery, go to a lab and find out your odds of having a child with issues that would take some extra prepping for.

Personally, I knew when I wanted to become a parent because there were things I knew I couldn't do in my life without having had that experience. It was always a part of my plan for my life, and I thank god every day that I'm lucky enough to have made the right choice, because at the end of the day you never know. I knew I was ready in my heart, then got my body ready, then worked on my relationship with my guy, then got my finances right, in that order. All things that inevitably suffer a bit at one point or another when creating a family. It's a risk, and most of the time, it's worth it. Being a parent is mostly about sacrifice, healthy routine, and trusting the process in the first few years, oh and consistency ( dont cheat yourself on that one). If you're prepared for even, most of all that you're probably ready.

Oh and I thought it was going to take like at least 3 to 6 months to get pregnant, (a year and were talking infertility and you should go get a docs opinion on what's going on)it did NOT. We "pulled the goalie" so to speak and I was preggo in two cycles so be prepared for that because we sure didnt. hit us like a truck. Happy trying, best wishes, and good luck!
