Do you think that when you approach your wife, even with the intentions of helping or supporting her, you come from a place of need? Like, are there, somewhere in the back of your mind or in your subconscious, expectations attached to your actions? If this is the case, your wife might push your help or any of your approaches away because she can sense the expectations (of approval, gratitude, attention etc) and doesn't feel capable right now of reciprocating. Your wife's batteries are simply empty, it seems. The difficult pregnancy, the childbirth and the childcare have taken a huge toll on her body, mind and soul, all at the same time. I think she's running on an empty tank right now, and doesn't have the emotional or mental resources to give you what you need. She only has enough to take care of the baby and that's about it right now.

Does any of this resonate with you as a possible explanation to what is going on with your wife? If the answer is yes, then here is what you could do: Give your wife some space. Don't approach her with expectations of reciprocation anymore. Try to fulfill your own needs as much as possible. Don't look to her for approval, recognition or gratitude. She is right now not on the same energy level as you are. So when you bring her articles to discuss, you are operating on a mental level that she is not on. (Btw, she might also be anemic and has a hard time concentrating, processing new information etc.) Please be understanding and have patience. Take care of yourself in the meantime. Give yourself everything that you need on your own for a while. You did sth well? Praise yourself! Be proud of yourself! You read sth interesting and want to discuss it? Call a friend. Reddit. Try to take this pressure off of your wife and watch her catching her breath. Things will improve, you'll see.

As for the baby, here's a little tip: Tell your wife how much you love the baby and how much you'd love to take care of it more, not in a needy way, as in "honey, why don't you let me take care of baby more?", but more in: I'd LOVE to do this, let's do this together. Don't frame it as helping her (which might put her on the defensive), frame it as being a team and doing things together for the baby you've created and now love together. Maybe this helps. Wish you all the best and congrats on the baby!
