Since you have already had the appendectomy
done, you can again try for the next child as soon as your wife feels perfectly alright. The overall status of the region where the appendix
was located before can be known after consultation with your physician who can either do a routine ultrasound
or if necessary a CT scan
of that region to know the status of the base of the appendix. If everything is normal, then you should go ahead with your next child. Hope this helps. Regards.
