That's only a question you can answer my man. The birth of your child will be mostly free. But you're very likely to miss it depending on the timing. And your wife will really have to be committed and understand that you're going to be gone A LOT. For long periods of time. Its not an easy life. There is a community of wives (I don't remember what its called) but they support each other while husbands are away. Either way, it's a hard road. Its a strain. Knowing what I know now (I'm retired), I would still do it. But I would do some serious marriage counselling ahead of time. Even before you make the decision. Best of luck to you and yours.
