How can a new parent prepare for having a baby?
Do the baby the birthing classes, where you get to learn everything that happens during birth.
Discuss with your partner what you both want out of the birthing experience; better do it before you are right in it.
Say "yes" to help when it is being offered, but also ask your friends and family to leave you alone; you just had a baby, that's totally okay.
Don't buy a ton of baby things. You don't actually need it.
Take Google with a grain of salt. Children are unique and other people's opinions may not apply to you. If you have a medical question, call your nurse. There are medical hotlines you can reach out to.
Plan your future vacations and put it on a calendar before you have a baby. This way you are committed.
