Quirks to be Aware of:

Baseless Installation

When the baby is using the preemie insert and you want to install the seat baseless, the lap portion of the seat belt may be pushing on their legs because of how the insert boosts the baby up. The baby we tried it out with experienced some discomfort from this, but she was too small to remove the insert. When she was 9 weeks old and this insert was removed, this was no longer an issue.
