Pull the feeding tube. If the child can be saved, the child must be saved in order to be baptized even at the cost of the mother's life. One of the risks of life as a woman is that you may die from pregnancy. Unfortunately, very few people are able to think rationally about this topic, and it is generally used to create specious justifications of direct murder of the child in order to prevent women from succumbing to one of the risks of their nature.
Really, its a simple question. Would you rather be responsible morally for the direct murder of a child (possibly your own), or the unintended but inevitable death or a mother (possibly your wife) from a natural medical condition? The answer to that sort of question, and the justifications attempted, says much about a person's character, IMHO.
(Not that I agree with the whole feeding tube thing anyway, but that is another story ...)
If the child is going to die anyway, killing the mother off just so that the child can be baptized would be a monstrously despicable act.

I'd rather save my wife, if the choice is between her and a fetus.
