She will get these and more quite often. Then there are the common complaints from the expectant mother herself. These include not being able to find nice maternity clothes, not being able to eat her favorite foods anymore, being constantly nauseous, not being comfortable sitting, standing, or lying down, swelling body parts, mood swings, etc. I've even heard women say that if their men really did love them, they would feel some of this pain. Men don't need sympathy pains to suffer during pregnancy.
Many men have to find out how to rearrange a budget to accomodate the new baby.
I'm not saying that women don't have a right to complain about the tribulations that come with pregnancy, either. Sometimes they suffer, too, although they aren't felt compelled to show it often. Men also feel like they sould have their place in the sun right along with the women. After all, the last Immaculate Conception took place about 2000 years ago. A lot of men feel as if they should get a piece of the attention as well.
