بسم الله الرحمن الرحيم
(Fatwa: 1033/801/D=9/1434)
(1) Instead of istikharah, you should supplicate Allah for pious and virtuous child and to pass all the stages easily.
(2) You may do so with the consultation of doctors. You should pay special attention towards the health of your wife.
Allah knows Best!
