I had a hellish first birth in the hospital because my husband wouldn't let me birth at home. I too am due in June. My husband can't wait for our homebirth. If I ask really nicely, maybe he'll send a post telling why homebirth is better for husbands than hospital births. Don't count on your husband reading anything to do with pregnancy.
Most men are too squeamish to even read the word 'vagina' much less the rest of it.
The best thing that we did was go to Bradley classes. They are pretty extensive and informative. Hey, I just had a thought. The support of other men is important. You might look for a homebirth support group.
