why does she have two infant carriers

this might’ve been mentioned already but i saw she has two car seat carriers for soon to be baby #2. i’m sorry why would you buy two carriers for a newborn? is there a point she’s trying to make that I just don’t understand and someone can explain. Why wouldn’t you just get two bases?! I have the same car seat the nuna aire rx for my newborn, we have a base in one car and a base in the other.

car seat always comes inside the house and is never left in the car overnight or during the day. im confused why you were to need two carrier infant seats for one baby. unless if im mistaken and the other one is not a carrier.
