Pregnancy is a HUGE deal for your wife.

While you may from time to time forget your wife is pregnant, your wife does not. She is changing physically, mentally and hormonally. Dads need to be involved as possible—go to medical appointments, rub cream on her belly, talk to the baby, ask her questions regularly about how she’s feeling. When you are exhausted, try to remember that she is probably even more so. And when the enthusiasm is waning, fake it.
