OK, for multiple babys, not sure how many you will have, you listen to only the kids music and only watch the kids show. This should work, though you may have to keep them in a room with the kids music playing while they do something. It worked the two times I tried it, and I got triplets both times, one set of boys, the other of girls, both in different stories. If you want to get a specific gender, I believe it's only eat apples for boys, and only eat watermelon for girls. Hope this help's you! Have fun :].

Not without mods or being lucky enough to experience a glitch. The Fertility Treatment lifetime reward does NOT allow you to have Quadruplets.
