Congratulations! That's so wonderful. I know that you both will be so happy. This is such a joyful blessing. Enjoy this time and learn everything you can right now, without overwhelming yourself. You will be a wonderful father. You can do this. You can do this. Your baby is so lucky to have you two for parents. He or she is very lucky because he is wanted and loved already. Look how you are protecting her already by not telling the real world about him yet. I understand that. I did that too. You will let everyone know when the time is right. Your daddy instinct has already kicked in. That's great. You are going to be a terrific daddy.
Congrats! Women go through different emotions when pregnant. The hormones rage out of control! Perhaps she wants to pass the danger zone and get to the second trimester. Making sure nothing goes wrong.
My best friend and her hubby told me a couple months ago that they were preggers! They only wanted family (yay I counted!) to know first. She then broke the news the other day on Facebook! I'm so excited for them and to become 'honorary auntie!'
Congrats man, I'm excited that your excited that makes us all excited weeeeeeeee.
Here are some tips from a guy who just became a daddy also:
-read as many baby books as you can, I found some baby books written just for new dads in waiting, they are the best find the one from "Peter Little" called "The baby book for fathers" don't know if they have it in English, mine is in Dutch.
-talk with your wife if she wants to deliver at home or in the hospital
-write down your favorite boy/girl names down
-begin to choose your doctor
-never be late on your doctor appointments
-go to your baby birth classes, forget what you see in the movies, what they teach you in those classes is quite different
-don't stress out your wife, but try to be as helpful as you can, even if you get irritated, don't let her see or sense that. Got this tip from another dad. Stress is bad for the baby.
-keep her away from junk food, even if she craves it, because she will. Give her plenty of vegetables, this would be a good time to learn how to cook. Or get a Turbo Cooker like me hahaha.
well there's a ton more, but I think the books will explain the rest.
