If you grow spider plants, you don't really need to do much to make them "have babies." Spider plants naturally produce root runners at the end of their stalks that can be simply removed and planted as new plants. All you need to do is properly care for your spider plant and it will do the rest of the work "making babies" on its own. Most offshoots will develop in the autumn when the days began to get shorter.

Grow your spider plant in a place where it gets indirect sunlight. Direct sunlight can burn its leaves and stunt its growth. Keep away from windows in the winter to avoid cold drafts.
Use general-purpose potting soil when planting a new spider plant. Use water-soluble or a time release houseplant fertilizer, following the directions on the label.
Allow the soil to dry out completely between waterings. Feel the soil each day before watering to make sure it's dry before adding water.
Maintain temperatures of 65 and 75 F during the day and 50 to 55 F at night for optimal temperatures.
Divide and repot your spider plant as it gets bigger. Otherwise it's roots may crack through the pot or container.
