Honestly, I don't have any children and I'm in the same situation as you, however, I have a baby sister (like, 20 years birth difference from her and I) and I worked for a pediatric doctors office, so, I'll share with you what parents have shared with me.

Nothing you can do can REALLY prepare you for having children. You may be nervous leaning how to become a parent, some things may not come naturally, but there are services and people out there who are MORE THAN HAPPY to help you and your significant other out. So if it doesn't, DON'T FREAK, however, DO tell your pediatrician if any aspect of being a mommy isn't coming easy for you. He or she can help or find you someone to help.

I've been told physically, start stocking up on diapers. Each paycheck, buy one more pack, because diapers can be expensive. I'd say for safe measure, buy some clothes too (you can usually find discounted/clearance clothing at the end of each season, like, fall clothes in the spring or summer in the fall). Possibly other items too, because babies can be expensive.

I also have decided myself how and what I want to handle my pregnancy. I advise other women to do the same and don't let people scare you away from certain things you may follow, and, decide on your own from your own research. I've never been one for hospitals, and also, I've had EMT training in delivering a baby in the field so, I have faith I can talk someone through delivering mine, thus, I want a home birth personally. I'm just a more natural person.

It probably wouldn't hurt for you to decide ahead of time weather you want to breast or bottle feed, if you want to have your child vaccinated or not and look into the vaccines, and try to find yourself a good pediatrician (which can honestly be a chore in itself) that has the same views on things as you do. Also you may want to decide in the future if you want to circumcise your child if it's a boy or not (my boyfriend thinks it's horrible XD and doesn't want his child to have one).

And make sure you talk things through with your significant other to get their views on how they want things to be as well. They may not be the one carrying the baby to term (and most don't really know what it's like) but, they may have some ideas of what they want too.

SAVE MONEY NOW! Kids are expensive. You can't be prepared to have kids. Each kid is different and once you have one of your own, its different than taking care of all those cousins and friends kids.

Its a great experience tho.
