Congratulations! Kids are great. (I have 2 surviving and they’re a lot of fun!) They’re a lot of work, but you reap the results of what you put into them.
Make sure you’re there for her through pregnancy. Jilly said it’s not always roses and sunshine for every woman. She’s right! Every pregnancy is different.
You don’t have to marry her (poor decision if you’re not in love with her) but you do have to be there. She will be primary care-giver of your child. You would do better to have a good relationship w/ her than a resentful one. Marrying someone you’re not in love with is a recipe for disaster.
Keep going to school, you have several months yet before the baby makes his or her appearance. Someone else suggested cramming in extra school. I second that.
I also STRONGLY recommend that you and the mother start researching health options for your baby. EVERYTHING should be questioned. Vaccines, circumcision (PM me for info on that), how to feed the baby, what to feed the baby (I’m a huge breastfeeding promoter), sleeping arrangements (we do part time co-sleeping but it doesn’t work for everyone), routines, carseats. yes, carseats are a big issue. You want the best “bang for your buck” so to speak and we can’t be having the little dumpling get hurt. There is GOBS of info out there. Don’t leave all the research and leg work to her. This is your baby, too. BE INVOLVED.
Stay faaaaar AWAY from the “What To Expect…” series of pregnancy and parenting books. They’re alarmist. Pick up Mothering Magazine, anything by Dr. William Sears and his wife Martha Sears is great, check out www.lalecheleague.org for breastfeeding information.
Make it a goal to be a good dad and a good co-parent to the baby’s mother.
