Are you supposed to give it to both? I had a dad who kept getting sick so I finally paid for the doctor's diagnosis. Besides telling me what was wrong with this dad and which medicines to give to him, they also told me that if I wanted more kids that I should probably give him the baby boost as well.

I first cured him and let him rest for the night (closed my game, but didn't pause it) because he was so exhausted. The next day when I saw that he wasn't sick any longer and was well rested, I gave him the baby boost shot and then had them try. No baby. Not just no multiples, but no baby at all. So, I waited till later in the day and tried again. Still no baby.

I only gave the dad a shot though, so are you supposed to give the shot to both parents? Oh, and I've never had a multiple yet, plus I can rarely even get a second child at all and when I have, they were 6 years apart in one family and 7 years apart in other. Although I did have one family that got to adopt two kids. Not at the same time, but a little boy first and then a little girl and they turned out to only be 3 years apart in age.
