Adding newborn to application

Hi, myself and my husband got our ITA in 2021. We did our re-medical last May and the hospital made an error and hadn’t sent my x ray. We found out in November and immediately sent my x ray. I am now expecting our first baby and have notified IRCC of the due date. Will they wait untill baby is born to issue COPR? If they issue PR before can my husband fly to Canada after the baby is born and can I add the baby and join my husband thereafter with the baby?

It’s best to contact IRCC with a web form to get the official answer. I don’t know the answer but I will tag a couple of people who may know or can recommend others

Thank you so much!
