on the sims 2 for the PC, you start with two sims who are in love, have then both relax on a bed together or have them cuddle in a hot tub. select "try for baby" and if it works there will be a chime and the "try for baby" option will no longer be there. wait a day and the sims stomach will "pop" slightly. she (or he) will stay like that for a day, then the next day the sims baby bump will get even bigger. and on the third day you have a new sim in the family! now if you have the PS2 version you can't have a baby, there are no children
no they don't grow to toddler's, it is baby's then kids and they stay as kids but some say the grow into adults after kids but I'm not sure? :)
