Can my husband add me to his health insurance at the same time he adds our newborn son?

My husband is going to add our newborn son to his health insurance, financially it makes sense for me to drop my coverage and also join under his plan (same employer, same plan but enrolled separately). Can he add me under the same qualifying event of adding our son or do we need to wait until open enrollment to add me to his plan?
--------------------
No, not until open enrollment. That qualifying event, is qualifying for your SON - being born. Not for you. Sorry.
