In laws coming to visit

My FIL wants to come and stay with us for 2 weeks around my due date. This is good because someone will be around with our 2 year old while we’re at the hospital.

Then my MIL wants to come and stay with us for 10 days about 2 weeks after my due date. This is already stressing me out. What can I do or say without hurting feelings? I feel like such a terrible person for having these feelings...
