Your wife is exhausted, even if she says she isn't. And if she isn't, she will be soon. She is trying to maintain tiny bits of sanity as they are chipped away by her hormones and all the 7 million people who have opinions about what she should and shouldn't be doing. She is constantly in pain. She is constantly battling tears because her hormones are stupid. You should be figuring out how to do little things to make her happy, to surprise her, before she becomes a mom either again or for the first time. You should be treating her like a lady, no, like a princess. You should be loving and patient and understanding. You should do anything that required bending, lifting, cleaning, standing, or emotional toil. You should be holding her at night even if you don't feel like it. You should not be trying to have sex with her because she is physically, mentally, emotionally, and potentially even literally unable to feel sexy, fun, spontaneous, or aroused. You should remember that this is all temporary. You should remind her that you love her even if she hasn't shown interest in anything but her doctor and the 57 pillows that are scattered on your bed in months. You should be telling her that she's beautiful, even if she hasn't touched her hairbrush in months. You should be rubbing her back before she asks. You should be thinking about how terrified she might be about the changes that are happening. You should be remembering that she wants to be everything to you and your kid(s). You should remember that even if this time is hard and you would like nothing better than a vacation from her with some hot young thing, that there will be a day that you miss this and miss her pregnant and miss life before kid(s). You should remember that it's going to get better...it really is.
