I, personally, don't use a signifactor in any spread. sometimes you are more 4 of pentacles about something than say Queen of cups.

now for the gender of the baby. I have actually been able to do this with some accuracy. of course there is a 50/50 chance so the odds are good anyway. I usually just ask the question tell me about the baby's gender. then I draw three cards. If a page or other court card shows up it's great that helps. if there is a dominate suit that could point to gender.
cups and pentacles are considered female energy
wands and swords are male energy.
