I agree with the "no-no" to the baby shower for a 2nd, unless it has been 5+ years since the 1st one or it is the opposite sex of the 1st baby. I just had my 2nd child 7 weeks ago, both are boys. My friends threw me a shower, but, they had a diaper shower instead, which I think is perfectly fine. Everyone that attends brings a package of diapers instead of a gift. Some friends did give more than just a package of diapers, but that was all that was asked of them. Then, your guests can spend what is comfortable for them since packages of diapers can range in size and price from $10-40. Just let everyone know they type you prefer when you send out the invites. As for the date, I would try and do it close the the beginning of December since after the holidays cuts it pretty close to your due date!
