lol...be prepared for sudden mood changes, try not to get upset with her, she cant help it. She will most likely get irritable and compulsive about cleaning. She may be happy one minute crying another, and it may be caused by nothing other than watching a cute baby commercial on tv...make sure you give her space when she requests it, it is difficult sharing a body with someone

....otherwise, just be comfoting and stick by her side. Emland is right, be interested in her doctors appointments, her ideas for a baby room, names, etc...every little detail is so important to her, and even if you could care less what color the diaper changing table should be, she does, and any input will be appreciated by her..lol. good luck dad, its a fun ride!
