Hi Amy

We have 2 yo twins and a 10 month old. We have the twins on either side and the 10month old in the middle. It was hard when he was in the seat was in the reverse position but now that he has turned around, it is heaps easier.

I am not sure how you will get Stella out of the car if she is in the middle and the twins are in the reverse position on either side?? From experience there is not a lot of room to get past 2 seats in the reverse postition. You may need to out the twins together.

My twins were both head down from the beginning to the end, so sorry can't help you there.
