Question:
Is it permissible to prepare breakfast for my wife or another person if I have not yet davened shacharis?
Answer:
It is permitted. Although we should not engage in work before davening, however work that is mitzva related is permitted. Helping one’s wife and caring for others is a mitzva, therefore it is permitted.
You should have a lot of nachas from her.
