I stumbled upon this Chart the other day and found it to be quite interesting.
Just for fun, for those of you who planned or are planning your pregnancy for the estimated delivery date why did you want the month or season that you were trying for? (Work related, hoping for a zodiac sign, not wanting to buy a maternity winter coat)
Is there a certain month you tried to avoid? and why? (Holidays, Sibling birthdays, etc)
