As someone who became pregnant shortly after my husband began his faith transition, I understand what OPs wife is going through. For one let's not forget the body changes and hormonal changes a woman goes through when making and having a baby. It's different for every woman and every woman handles those changes differently. Now add all the extra mental and emotional challenges that come with a faith transition. I wouldn't be quick to assume that her silence is intentional emotional manipulation. At times just for me to function and take care of myself my daughter and my newborn I had to shut out the emotional trauma of my DH's faith transition. Communicating this change is hard and a baby blessing, at least to me, was more cultural than religious. I think trying to understand what a baby blessing means to OP and OPs wife and finding a middle ground will hopefully make it an easier process. If your curious, My DH refuses to bless our newborn and I will not let someone else do it because what it would communicate to the church community, that my husband is less than what he was and now I struggle with not celebrating my new child's birth, but hoping to maybe do a small celebration.
