Before my husband and I got married, we went to marriage preparation classes. We sat with a dozen or so other engaged couples, and discussed marriage and relationship issues. As the group started to dwindle, we realized many of the topics discussed were new conversations for some of the couples (and those conversations were the cause of a few breakups). Among other things, I learned that when it comes to important life decisions, you need to have a talk. So, yes, there are definitely questions you should absolutely ask your partner before you get pregnant.
Becoming a parent can be stressful, to say the least. If you're not on the same page as your partner and in agreement on some major childcare and family issues, problems can arise and what is already considered to be taxing and exhausting, can become downright impossible. Many parental decisions on important issues are decided upon before people even think about having children. We can be influenced by the way we are raised or by a rejection of how our own parents did things. Sometimes we can be convinced by our own reading or research on a topic, or we might be swayed by the techniques or routines practiced by our friends or even celebrities.
Whatever factors influence our choices, it's important to talk about these issues with our partner way before we see those little lines on the pregnancy test.
