Third row car seat

Ok... mommas with a two year old and a new baby on the way... I have a car with three rows but the middle row has captains seats so there’s no middle seat. Those who have experienced this same issue, do I move the two year old to the third row so there’s a seat for me beside the baby until he gets older or do I keep them both in the middle and just not sit in the back with baby? Suggestions???
